Back

Yes, SAS Similarity

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but not necessarily the same size.

Front

What is the AA Similarity Postulate?

Back

If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Front

What is the SSS Similarity Theorem?

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the SAS Similarity Theorem?

Back

If two sides of one triangle are in proportion to two sides of another triangle and the included angles are congruent, then the triangles are similar.

Front

What is a dilation in geometry?

Back

A transformation that changes the size of a figure but not its shape.
