Ratios and Proportions (Refresher: definitions, mean, extreme, cross product, properties)

Dilations (properties, definition, ± scale factors, notation, examples)

Stretches (vertical and horizontal dilations)

Similar Figures (definitions, similarity transformations)
Measurements in Similar Figures (perimeters, areas, volumes)

Methods of Proving Similar Triangles (AA, SSS, SAS and proofs of each method)
Proof Problems for Similar Triangles (3 common styles of similar proof questions)

"Side Splitter" Theorem (theorem, converse, proofs, example)
"Centroid" Theorem (theorem, proof, example)
Angle Bisector Theorem (theorem, proof, example)
 

Numeric and Algebraic Problems with Similarity (AA, strategies, side-splitter thm)
More Numeric and Algebraic Problems with Similarity (AA, SSS, SAS)

Construct: Dilations (similar Δs using AA, scalar/center, links to Construction section.)

 
Similarity in relation to right triangles appears under Right Triangles.
Similarity in relation to circle proofs appears under Circles


PRACTICE:
Practice with Dilations (objects, lines, triangles, coordinate plane)

Practice with Similarity (numerical/algebraic problems - AA)
More Practice with Similarity (numerical/algebraic problems; AA - SSS - SAS)

 



REFRESHER: (while these topics are mostly "review", you may also find new information here)
