Question

class 9 lesson coordinate geometry introduction​

Answer 1

Answer:

Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points. Using coordinate geometry, it is possible to find the distance between two points, dividing lines in m:n ratio, finding the mid-point of a line, calculating the area of a triangle in the Cartesian plane, etc. There are certain terms in Cartesian geometry that should be properly understood.

Answer 2

Answer:

We can represent a point in plane (called a cartesian plane or a coordinate plane) by means of an ordered pair of real numbers, called the coordinates of that point. The branch of mathematics in which geometrical problems are solved using coordinate systems in known as Coordinate Geometry.
