COORDINATE PROOFS AND TRANSFORMATIONS

In this unit, you will examine proofs of geometry theorems through coordinate geometry. You will then explore mappings of pre-images onto images. You will use the coordinate plane to define transformations. There are four basic types of transformations: reflections, translations, rotations, and dilations.
