* CCSS and PARCC specifically mention AA in relation to similar triangles. Engage NY also mentions SSS and SAS methods.
Engage NY specifies dilations not centered at the origin.
 LESSONS: * calculator link
Dilations (properties, definition, scale factors, use on coordinate axes)
 Stretches (vertical and horizontal dilations) not specified in CCSS/PARCC
Similar Figures (definitions, similarity transformations)
 Proving Similar Triangles (AA (proof), SSS, SAS) see * above
"Side Splitter" Theorem (theorem, converse, proofs, example)
 (theorem, proof, example) not specified in CCSS/PARCC
Measurements in Similar Figures (perimeters, areas, volumes)
Proof Problems for Similar Triangles (similar triangles, proportions, products)
Construct: Similar Triangles (Note: this links to Construction section.)

Similarity in relation to Circles Proofs appears under Circles

 PRACTICE: • Practice with Dilations • Practice with Dilations and Lines • Practice with Similarity (numerical problems) • Practice with Similarity Measurements • Practice with Side Splitter Theorem • Practice with Angle Bisector Theorem • Practice with Similarity Proofs

 REFRESHERS: (while these topics are mostly "review", you may also find new information here) * • Transformations - Dilations (intuitive, similarity, on coordinate axes) Note: this links to the Transformation section. • Ratios and Proportions (rules, properties)
