# Co – ordinate geometry Questions and Answers

# Co - ordinate geometry Questions

## Definition of Co - ordinate geometry

**The study of geometry using coordinate points is called coordinate geometry. By using this geometry distance between two points can be calculated by dividing the line in m:n ratio or finding midpoint or calculating the area of the triangle in a Cartesian plane.**

**Rules**

- When the x and y axis intersect at a point then it is called origin. Both x and y tend to be 0.
- The values are positive on the right hand side of the x-axis and the values are negative on the left hand side of x axis.
- The value on the upper side of the y axis tend to be positive and the value below tend to be negative.
- By a set of two numbers a point on the plane can be located. First value will be of x axis and second value will be of y-axis which will determine the unified position on the plane.
