Similar Triangles Proofs

Front

What are similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

What does AA ~ mean in triangle similarity?

Back

AA ~ means 'Angle-Angle Similarity'. If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

What does SAS ~ mean in triangle similarity?

Back

SAS ~ means 'Side-Angle-Side Similarity'. If two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, the triangles are similar.
