Theorems on Similarity

Proving theorems about triangles using similarity. Applying congruence and similarity criteria for triangles to solve real-world problems and to prove relationships in geometric shapes that we see around us.

Mapped to CCSS Section# HSG.SRT.B.4, HSG.SRT.B.5

Prove theorems about triangles. Theorems include: a line parallel to one side of a triangle divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle similarity. Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
