Analytical geometry or analytic geometry is also known as Cartesian geometry or coordinate geometry. It is a branch of mathematics which is a link between algebra and geometry. Analytical geometry deals with algebraic representation of geometrical figures. It pertains to representation of geometrical figures on a coordinate system.
