  • Coordinate Geometry

Do you remember what a plane is? A plane is any flat surface which can go on infinitely in both of the directions. Now, if there is a point on a plane , you can easily locate that point with the help of coordinate geometry. Using the two numbers of the coordinate geometry, a location of any point on the plane can be found. Let us know more!

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates .

What are Coordinates?

Now, to help you understand the coordinates, take a look at the figure below.

case study on coordinate geometry class 8

Now, consider the grid on the right. The columns of the grid are labeled as A, B, C, D, E, F, etc. On the other hand, the rows are numbered as 1, 2, 3, 4, 5, 6, and so on. You can see that the letter X is located in the box D3 i.e. column D and row 3.  Here, D and 3 are the coordinates of this box.

The box has two parts – one is the row and the other is the column. You need to understand that there are several boxes in every row and several boxes in every column. So, when you have both of them, you can find one single box that is the point where the rows and the columns intersect each other.

The Coordinate Plane

In the coordinate geometry, all the points are located on the coordinate plane. Take a look at the figure below.

case study on coordinate geometry class 8

The figure above has two scales – One is the X-axis which is running across the plane and the other one is the y-axis which is at the right angles to the X-axis. This is similar to the concept of the rows and columns that we discussed in the first part above.

Understanding the Concept of Coordinates

  • The point of intersection of the x and the y-axis is known as the origin . At this point, both x and y are 0.
  • The values on the right-hand side of the x-axis are positive and the values on the left-hand side of the x-axis are negative.
  • Similarly, on the y-axis, the values located above the origin are positive and the values located below the origin are negative.
  • When you have to locate a point on the plane, it is determined by a set of two numbers . So, first, you have to write about its location on the x-axis followed by its location on the y-axis. Together, the two will determine a single and unique position on the plane.

So, in the figure above, the point A has a value 20 on the x-axis and value 15 on the y-axis. These are also the coordinates of the point A. Often these points are also regarded as the “rectangular coordinates”. Please note: The order of the points on the plane is crucial. You have to write the x coordinate ahead of the y coordinate.

Things That Have Been Made Possible By Coordinate Geometry

If you know the coordinates of a group of points, you can do the following:

  • Determine the distance between these points.
  • Find the equation , midpoint, and slope of the line segment.
  • Determine if the given lines are perpendicular or parallel.
  • Find the perimeter and the area of the polygon formed by the points on the plane.
  • Transform the shape by reflecting, moving and rotating it.
  • Define the equations of ellipses , curves , and circles .

Question For You

Question 1: What is the name of horizontal and vertical lines that are drawn to find out the position of any point in the Cartesian plane?

Answer : The name of horizontal and vertical lines that are drawn to find out the position of any point in the Cartesian plane are determined by x-axis and y-axis respectively.

Question 2: Who is the father of coordinate geometry?

Answer:   The father of coordinate geometry was René Descartes. He was referred to as the father of analytical geometry due to his contributions to the field. As his Latin name was Renatius Cartesius, thus we learn that the terms ‘Cartesian plane’ and ‘Cartesian coordinate system’ were a derivative of this man’s name.

Question 3: What do we need to coordinate geometry for?

Answer: Coordinate geometry is needed to offer a connection between algebra and geometry with the use of graphs of lines and curves. It is an essential branch of math and usually assists us in locating points in a plane. Moreover, it also has many uses in fields of trigonometry, calculus, dimensional geometry and more.

Question 4: What is Section Formula?

Answer: Section formula helps us knowing the coordinates of the points that are dividing a given line segment into two parts. This allows the lengths to be in the ratio m: n m: n m: n. Thus, the midpoint of a line segment is the point which divides a line segment into two equal halves.

Question 5: What is the definition of coordinate geometry in math?

Class 8 Chapter-22 Introduction to Coordinate Geometry

Geometry is a branch of Mathematics that is related to the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs. It is mainly concerned with properties related to distance, shape, size, and relative position of figures. Applications of Geometry in the real world will enlighten you in areas that include computer-aided design for construction blueprints, the design of assembly systems in manufacturing, nanotechnology, computer graphics, visual graphs, video game programming, and virtual reality creation.

Geometry is also used in many scientific and technical areas, such as mechanics, astronomy, crystallography, engineering, architecture, geodesy, aerodynamics, and navigation.  Geometry is easily present everywhere in nature, as we discover more and more about our environment and our surroundings we see so many simple Examples such as spheres, triangles, squares, lines, etc.  

Various Ways on How Geometry is Used in Everyday Activity in Our Lives

The major use of Geometry is in the construction field. They are used for designing plans for building dams, temples, roads, homes, monuments, etc.

It is very helpful in the science industry in scientific research methods and also in measuring orbits and planetary motions.

Geometry allows you to determine and figure out how shapes and figures fit together to maximize efficiency and visual appeal in real life .

Geometry is used for computer imaging, designing, creating video games, animations, and things like that are made using geometric concepts. 

 Some important professions like the medical industry benefit from geometric imaging. Technologies such as MRIs and CT scans are most efficiently used both for surgical aids and diagnosis.

A Mathematician usually applies Mathematical techniques and theories to real-life problems to effectively solve them in a proper method. Their main duties include gathering and analyzing research data, resolving challenges in other sectors like government, science, engineering, and business, uncovering and finding unknown relationships between various Mathematical principles, and using models to resolve problems and present solutions to necessary leadership teams.

Lots of young budding Game developers or video game developers, create video games for various systems, design mobile applications, computers, and consoles. Their other major responsibilities include coding the bases for the games, troubleshooting and testing designs to fix any major issues, and assisting in the development of characters, levels, or storylines further.

Practice Questions on Coordinate Geometry

In this article, we will learn about one interesting topic which is covered in class 9 and class 10 mathematics. We will look at some formulas and problems of Coordinate Geometry .

Important Formulas

General Form of a Line : Ax + By + C = 0 Slope Intercept Form of a Line : y = mx + c Point-Slope Form : y − y1= m(x − x1) The slope of a Line Using Coordinates : m = Δy/Δx = (y2 − y1)/(x2 − x1) The slope of a Line Using General Equation : m = −(A/B) Intercept-Intercept Form : x/a + y/b = 1 Distance Formula : |P1P2| = √[(x2 − x1) 2 + (y2 − y1) 2 ] For Parallel Lines : m1 = m2 For Perpendicular Lines : m1m2 = -1 Midpoint Formula : M (x, y) = [½(x1 + x2), ½(y1 + y2)] Angle Formula : tan θ = [(m1 – m2)/ (1 + m1m2)] Area of a Triangle Formula = ½ |x1(y2−y3)+x2(y3–y1)+x3(y1–y2)| Distance from a Point to a Line : d = [|Ax 0 + By 0 + C| / √(A 2 + B 2 )]

Practice Problems with Solutions:

Q1. find the equation of a line which passes through the points (3, 4) and (5, 8) in the general form..

To find the equation of a line in the general form, follow these steps: Step 1: Find the slope (m): m= (8-4)/(5-3) m = 2 Step 2: Use the point slope form through (3, 4) y – 4 = 2(x – 3) y – 4 = 2x – 6 y = 2x – 2 Step 3: Now, convert to the general form 2x – y – 2 =0

Q2. Find the equation of a line passing through the point (2, 3) with slope 2 in slope-intercept form y=mx+c.

The point-slope form equation of line is y – y1 = m(x – x1) Given point = (2, 3) slope = m =2 Now, y – 3 = 2(x – 2) y – 3 = 2x – 4 y = 2x – 1 So, the equation of a line passing through the point (2, 3) with slope 2 is y = 2x – 1.

Q3. Find the slope of the line passing through the points (2, 5) and (6, 9).

To find the slope of the line passing through the points (2, 5) and (6, 9), use the following formula m = (y2 – y1)/(x2 – x1) m = (9 – 5)/(6 – 2) m = 1. So, the slope of the line passing through the points (2, 5) and (6, 9) is 1.

Q4. Find the equation of a line with x-intercept 4 and y-intercept 5 in intercept-intercept form x/a+y/b=1.

Given, x-intercept = 4 y- intercept = 5 equation of line = x/a + y/b = 1. x/4 + y/5 = 1 5x + 4y = 20. So, the equation of a line with x-intercept and y-intercept is 5x + 4y = 20.

Q5. Find the distance between the points (2, 3) and (5, 7) using the distance formula.

The distance formula is d = √[(x2 − x1) 2 + (y2 − y1) 2 ] Given points are (2, 3) and (5, 7). Now, d = √[(5 – 2) 2 + (7 – 3) 2 d = √(3) 2 + (4) 2 d = √9 + 16 d = √25 d = 5 So, the distance between the points (2, 3) and (5, 7) is 5.

Q6. Determine if the lines with equations 2x+3y−5=0 and 4x+6y−10=0 are parallel.

To check whether the given pair of lines are parallel, we need to check their slope if m1 = m2, then they are parallel. Now, to calculate slope of first line 2x + 3y -5 = 0 m1 = -(a/b) m1 = -2/3 Now, we calculate slope of second line 4x + 6y – 10 = 0 m2 = -(a/b) m2 = -(4/6) m2 = -2/3 Here, m1 = m2 So, the lines 2x + 3y – 5 = 0 and 4x + 6y – 10 = 0 are parallel lines.

Q7. Determine if the lines with equations 3x+4y−7=0 and 4x−3y−5=0.

To check whether the given pair of lines are perpendicular, we need to check their slope if m1.m2 = -1, then they are perpendicular. Now, to calculate slope of first line 3x + 4y – 7 = 0 m1 = -(a/b) m1 = -3/4 Now, we calculate slope of second line 4x – 3y – 5 = 0 m2 = -(a/b) m2 = -(4/-3) m2 = 4/3 now, m1.m2 = (-3/4).(4/3) = -1 So, the lines 2x + 3y – 5 = 0 and 4x + 6y – 10 = 0 are perpendicular lines .

Q8. Find the midpoint of the line segment with endpoints (1, 2) and (5, 8).

to find the midpoint use the following formula M(x, y) = [(x1 + x2)/2, (y1 + y2)/2] now, M(x, y) = [(1+5)/2, (2+8)/2] M(x, y) = [6/2, 10/2] M(x, y) = (3, 5) Hence, the middle point is (3, 5).

Q9. Find the area of the triangle formed by the vertices (4, 5), (10, 12) and (-3, 2).

To find the area use the following formula Area = ½ |x1(y2−y3)+x2(y3–y1)+x3(y1–y2)| so, area of triangle = x1y2 – x1y3 + x2y3 – x2y1 + x3y1 – x3y2 area of triangle = 1/2 [4×12 – 4×2 + 10×2 – 10×(5) + (-3)×5 – (-3)×12] area of triangle = 1/2[48 – 8 + 20 – 50 – 15 + 36] area of triangle = 1/2[71] area of triangle = 71/2 So, the area of triangle is 71/2.

Q10. Find the distance from the point (2, 5) to the line 3x+4y−12=0.

To find the distance from a point to the line , use this formula d = [|Ax0 + By0 + C| / √(A 2 + B 2 )] Now, given line = (Ax + By + C = 0) = 3x + 4y -12 = 0 so, A = 3, B = 4 and C = -12 given point = (x0, y0) = (2, 5) So, x0 = 2, y0 = 5 d = [|Ax0 + By0 + C| / √(A2 + B2)] d = [|3 × 2 + 4 × 5 – 12| / √(3 2 + 4 2 )] d = [|6 + 20 – 12| / √(9 + 16)] d = [|14| / √(25)] d = 14/5 So, the distance from a point (2, 5) to the line (3x + 4y – 12 = 0) is 14/5
