Geo Unit 5 Similarity Unit Review

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but different sizes.

Front

What is the similarity statement for the triangles ΔMNL and ΔOPQ?

Back

ΔLMN ∼ ΔPQO

Front

Are the following triangles similar? Why or why not?

Back

No, the ratios of the corresponding sides are not equal.

Front

In similar polygons, how are corresponding sides and angles related?

Back

Corresponding sides are proportional, and corresponding angles are congruent.

Front

Are the triangles ΔABC and ΔDEF similar?

Back

No.

Front

What does it mean for two triangles to be similar?

Back

It means that their corresponding angles are equal and the ratios of their corresponding sides are proportional.

Front

If two triangles have one angle equal and the sides including that angle are proportional, what can be concluded?

Back

The triangles are similar.

Front

What is the relationship between the sides of similar triangles?

Back

The ratios of the lengths of corresponding sides are equal.

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

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

Front

How can you determine if two polygons are similar?

Back

Check if their corresponding angles are congruent and the ratios of their corresponding sides are proportional.
