Unit 6 Test (Similarity)

Front

What is the definition of similar triangles?

Back

Triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does AA Similarity stand for?

Back

AA Similarity means that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SSS Similarity stand for?

Back

SSS Similarity means that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

Front

What does SAS Similarity stand for?

Back

SAS Similarity means that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

How do you solve a proportion?

Back

To solve a proportion, cross-multiply and then divide to find the unknown variable.

Front

What is the scale factor in similar triangles?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar figures.

Front

If triangle ABC is similar to triangle DEF, what can be said about their angles?

Back

The corresponding angles of triangle ABC and triangle DEF are equal.

Front

If the scale factor of two similar triangles is 2, what does this mean?
