Front

Are the figures similar? Explain.

Back

No, not similar.

Front

What is the definition of similar figures?

Back

Figures 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, the triangles are similar.

Front

What is the SSS Similarity Theorem?

Back

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

Front

What is the SAS Similarity Theorem?

Back

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

Front

How do you find the scale factor between two similar figures?

Back

Divide the length of a side of one figure by the corresponding side of the other figure.
