Unit 8 Test Review -Geometry - Similar Triangles

Front

What is the AA similarity theorem?

Back

The AA (Angle-Angle) similarity theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Front

What does SAS similarity theorem stand for?

Back

SAS (Side-Angle-Side) similarity theorem states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are congruent, then the triangles are similar.

Front

What is the SSS similarity theorem?

Back

SSS (Side-Side-Side) similarity theorem states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

Front

If two triangles are similar, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are congruent.

Front

If two triangles are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar triangles are proportional.

Front

What is a scale factor in similar triangles?

Back

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

Front

How do you determine if two triangles are similar using the AA criterion?

Back

To determine if two triangles are similar using the AA criterion, check if two angles of one triangle are equal to two angles of the other triangle.

Front

What is the relationship between the areas of two similar triangles?

Back

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.

Front

If triangle ABC is similar to triangle DEF, and the length of side AB is 6 and side DE is 3, what is the scale factor?

Back

The scale factor is 2:1.

Front

If triangle XYZ is similar to triangle PQR, and the angles of triangle XYZ are 30°, 60°, and 90°, what are the angles of triangle PQR?

Back

The angles of triangle PQR are also 30°, 60°, and 90°.
