Coordinate Geometry
Coordinate geometry, or analytic geometry, is the study of geometry using an algebraic representation of a specified coordinate system to find and analyze relations between geometric figures. Wolfram|Alpha has knowledge about many geometric figures and is capable of determining the algebraic equations for them and computing geometric properties.
