Unit 6 Test (Similarity)

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size. This means their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is AA Similarity?

Back

AA Similarity (Angle-Angle Similarity) states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is SSS Similarity?

Back

SSS Similarity (Side-Side-Side Similarity) states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is SAS Similarity?

Back

SAS Similarity (Side-Angle-Side Similarity) states that 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 do you solve for x in similar figures?

Back

To solve for x in similar figures, set up a proportion using the lengths of corresponding sides and solve for x.

Front

If triangle ABC is similar to triangle DEF, and AB = 6, DE = 9, what is the ratio of their sides?

Back

The ratio of their sides is 6:9, which simplifies to 2:3.

Front

What is the formula for finding the length of a side in similar triangles?

Front

What is the significance of corresponding angles in similar triangles?

Back

Corresponding angles in similar triangles are equal, which is a key criterion for establishing similarity.

Front

If two triangles have one angle equal and the sides including that angle are in proportion, what similarity criterion applies?

Back

The SAS Similarity criterion applies.
