**Common Core**- HSG.SRT.A – Understand similarity in terms of similarity transformations
- HSG.SRT.B.5 – Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.

**TEKS**- G.7(A) – apply the definition of similarity in terms of a dilation to identify similar figures and their proportional sides and the congruent corresponding angles
- G.7(B) – apply the Angle-Angle criterion to verify similar triangles and apply the proportionality of the corresponding sides to solve problems
