Proving Triangles Similar AA ~ Postulate: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. (AA~) SSS ~ Theorem: If the measures of the corresponding sides of two triangles are proportional, then the triangles are similar. (SSS~) SAS ~ Theorem: If the measures of two sides of a triangles are proportional to the measures of two corresponding sides of another triangle and the included angles are congruent, then the triangles are similar. (SAS~) 1. If ∆𝑅𝑆𝑇~∆𝑋𝑌𝑍, write the proportionality statements for the side lengths. Are the triangles below similar? If so, write a similarity statement and verify it. 2. ___________________ 3. __________________ 4. ____________________
