Unit 6: Coordinate Geometry

Unit six is about using the coordinate plane to prove the similarity and congruence relationships from previous units analytically. Students use coordinates to verify geometric relationships by finding slope and distance of a line to support their proof. This unit provides students with the opportunity to refine their understanding of basic geometric theorems and transformations.
