Important Topics for RS Aggarwal Class 10 Maths Solutions Chapter 6: Coordinate Geometry

Basics of a Cartesian Plane

Any point on a given plane can be located by a pair of numbers that are known as the coordinates. The distance of a given point from the y-axis is called abscissa or x-coordinate. The length of any given point from the x-axis is known as ordinates or y-coordinate.

Distance Formula: The following formula gives the distance of any two points A (x1, y1) and B(x2, y2)-


Section Formula

If any point P(x,y) that divides the line segment which is joining A(x1, y1) and B(x2, y2) internally in let’s suppose the ratio m:n, then, the coordinates of the point P can be calculated by the section formula given as-

P(x,y)= {(mx2+nx1)/(m+n), (my2+ny1)/(m+n)}


The midpoint of the line segment always divides it in the ratio of 1:1. Therefore the coordinates of that midpoint of the line segment joining points A(x1, y1) and B(x2, y2) is given by the following formula-

p(x,y) = [ (x1+x2)/2 , (y1+y2)/2 ]

Centroid of a triangle

If some points A(x1, y1), B(x2, y2) and C(x3, y3) are the three vertices of a triangle ABC, then we can calculate the coordinates of its centroid which is given as-

C(x,y) = [ (x1+x2+x3)/3 , (y1+y2+y3)/3 ]

Area from Coordinates

The area can be calculated from a formula if the vertices of the triangle are given. If we suppose as A(x1,y1), B(x2,y2) and C(x3,y3) be the three vertices of a Δ ABC, then the area is calculated by the following formula-

A= 1/2[x1(y2−y3)+x2(y3−y1)+x3(y1−y2) ]

Important Notes 

  1. If we take the points A, B, and C in the anticlockwise direction, then the area obtained will be positive. 
  2. If we take the points in the clockwise direction, then the area will come out to be negative. Therefore we take the absolute value every time we calculate the area.
  3. If the area of a triangle is coming out to be zero, then it means that the three points are collinear.
