Unit 8 Similar Triangles Retest

Front

What does AA ~ Theorem state about triangles?

Back

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

Front

What does SSS ~ Theorem state about triangles?

Back

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

Front

What does SAS ~ Theorem state about triangles?

Back

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

Front

How can you determine if two triangles are not similar?

Back

If none of the similarity criteria (AA, SSS, SAS) are satisfied, the triangles are not similar.

Front

What is the formula to find the missing side in similar triangles?

Back

Front

If triangle ABC is similar to triangle DEF, and the lengths of sides AB and DE are 4 and 8 respectively, what is the ratio of their sides?

Back

Front

If two triangles have angles measuring 30°, 60°, and 90°, what can be concluded about the triangles?

Back

The triangles are similar by the AA ~ Theorem.

Front

Back

The value of x is 10.

Front

If triangle XYZ has sides of lengths 5, 12, and 13, and triangle PQR has sides of lengths 10, 24, and 26, are the triangles similar?

Back

Yes, they are similar by the SSS ~ Theorem.

Front

What is the first step to determine if two triangles are similar?

Back

Check if any pairs of angles are equal (AA ~ Theorem).
