Learn **what is coordinate geometry**? Co-ordinate geometry is also called **analytical geometry** and also called as **Cartesian** **geometry.** Rene Descartes is the person who introduced co-ordinate geometry to the world.

The first question that arises when we start learning co-ordinate geometry is **what is coordinate geometry**? Without knowing co-ordinate geometry definition if you are learning only topics in co-ordinate geometry then no use. So my suggestion is before learning any chapter first try to know its meaning and definition.

**What is coordinate geometry definition?**

**Co-ordinate geometry** is the **branch of the mathematics which deals with studying of geometry with the help of co-ordinate system**. Second definition of co-ordinate geometry is the “**branch of mathematics which combines Algebra and Plane Geometry**”.

Here you may get doubt that what is coordinate system. Drawing two perpendicular lines in a plane and representing horizontal as x-axis and vertical line as y-axis and intersection point of these two lines as origin. The entire system so formed is called as **co-ordinate system.**

Hope that co-ordinate geometry definition you understood. From now if anyone asks you **what is coordinate geometry** then give any one of above two definitions.
