## Important Topics for NCERT Exemplar Class 10 Maths Solutions Chapter 7: Coordinate Geometry

Basic Terms in Coordinate Geometry

1. Abscissa: This is the x-coordinate of a point, which means it is the distance of a given point from the y-axis.
2. Ordinate: This is the y-coordinate of a point, which means it is the distance of a given point from the y-axis.

Distance Formula

If we consider 2 points with their coordinates as P(x2, y2)and Q(x1, y1), then the distance between these points can be given by the distance formula such that, Note that the distance is always a positive value.

The distance of the point P(x, y) from the origin O(0, 0) is given such that, Section Formula

If a point P divides a given line segment internally, with end-points as A(x1, y1)and B(x2, y2)into a ratio m1:m2, then the coordinates of the point P are given as Therefore, if we are to find the mid-point of a line segment with end-points P(x1, y1)and Q(x2, y2), the coordinates will be given as Area of a Triangle and Collinearity of 3 Points

If we have the three vertices of a triangle with their coordinates as A(x1, y1), B(x2, y2) and C(x3, y3), then the area of the triangle ABC is given as If we have to check the collinearity of three points, the area of the triangle formed by them should be zero.
