Description:

In this worksheet of eight questions, students practice their knowledge of similarity proofs. In the first four questions, students determine which postulate or theorem works to prove triangle similarity - AA, SAS, or SSS. In the last four questions, students are asked to work through the proof of various problems. The answers are embedded in the page, and this is a helpful resource for students to work with similarity proofs.

CCSS.Math.Content.HSG-SRT.A.2: Common Core State Standards for Mathematics

Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides.
