Similar Triangles Unit 4 Review

Front

What does AA~ stand for in triangle similarity?

Back

AA~ stands for Angle-Angle similarity, which states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What does SSS~ stand for in triangle similarity?

Back

SSS~ stands for Side-Side-Side similarity, which states that if the corresponding sides of two triangles are in proportion, the triangles are similar.

Front

What does SAS~ stand for in triangle similarity?

Back

SAS~ stands for Side-Angle-Side similarity, which states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

How can you determine if two triangles are not similar?

Back

Two triangles are not similar if none of the AA~, SSS~, or SAS criteria are met.

Front

What is an alternate interior angle?

Back

An alternate interior angle is formed when a transversal crosses two parallel lines, creating pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

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

Back

If two shapes are similar, their corresponding angles are equal.

Front

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

Back

If two shapes are similar, their corresponding sides are in proportion.

Front

Given two similar triangles, if one triangle has sides of lengths 4, 6, and 8, what are the lengths of the corresponding sides of the other triangle if the scale factor is 2?

Back

The lengths of the corresponding sides of the other triangle would be 8, 12, and 16.

Front

If triangle ABC is similar to triangle DEF, and the length of side AB is 5 and side DE is 10, what is the scale factor?

Back

The scale factor is 2.

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 side lengths.
