This collection of worksheets always involve proofs of geometric theorems that utilize general points on a Cartesian Plane You will need to make several arguments over the course of the series Make sure that you explicitly state each argument clearly These worksheets explains how to do coordinate geometry proofs with triangles and Typically we use three theorems to establish the similarity of the triangles The three theorems involved are side angle side SAS Angle Angle AA and Side Side Side SSS Angle Angle AA Theorem Angle Angle AA theorem says that two triangles are similar if the two pairs of their corresponding angles are congruent
