Historically, the place where people are grounded in this is plane geometry. In carrying out proofs of properties from plane geometry, one not only learns some useful geometry but also develops important analytical thinking capabilities.

This blending of algebra and geometry is referred to as analytic geometry. Because this process often involves placing geometric figures in a coordinate plane, it is also more commonly known as coordinate geometry. Coordinate geometry proofs employ the use of formulas such as the Distance Formula, the Slope Formula and...

Proofs. A proof in geometry requires a series of steps. That series may consist of only one step, or it may ... Euclidean geometry dealt originally with two general kinds of figures: those that can be represented in two dimensions (plane geometry) and those that can be represented in three dimensions (solid geometry).
