Chapter 7 Review

Front

What does AA~ mean 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~ mean 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~ mean 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 do you determine if two triangles are similar?

Back

You can determine if two triangles are similar by checking for AA~, SSS~, or SAS~ conditions.

Front

If triangle NPQ is similar to triangle RTS, what is the scale factor if NPQ has sides of 4 and RTS has sides of 5?

Back

The scale factor is 4:5.

Front

Solve for x: 2x + 3 = 4.

Back

x = 0.5.

Front

What is the similarity statement for triangles that are similar by AA~?

Back

The similarity statement indicates which triangles are similar, e.g., Triangle A ~ Triangle B.

Front

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

Back

Their corresponding angles are equal.

Front

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

Back

The ratio of their sides is 6:9 or 2:3.

Front

Solve for x: 3x - 5 = 16.

Back

x = 7.
