Unit 4a Test Review

Front

What is the AA postulate in triangle similarity?

Back

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

Front

What is the SAS postulate in triangle similarity?

Back

The SAS (Side-Angle-Side) postulate 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 postulate in triangle similarity?

Back

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

Front

What does it mean for triangles to be similar?

Back

Triangles are similar if they have the same shape but not necessarily the same size, meaning their corresponding angles are equal and their corresponding sides are proportional.

Front

If triangle ABE is similar to triangle DBC by SAS postulate, what can be inferred about their sides?

Back

The corresponding sides of triangles ABE and DBC are proportional.

Front

Back

Cross-multiply to get: 32 * 6 = 48 * x. Thus, x = 4.

Front

What is the relationship between the sides of similar figures?

Back

Corresponding sides of similar figures are proportional.

Front

If triangle BCA is similar to triangle EFD by AA postulate, what can be said about their angles?

Back

The corresponding angles of triangles BCA and EFD are equal.

Front

What is the value of y if triangles are similar and the corresponding sides are in the ratio 2:1?

Back

If the ratio of the corresponding sides is 2:1, then y can be calculated based on the given side lengths.

Front

What is a similarity statement?

Back

A similarity statement indicates which triangles are similar and is written in the form: Triangle A ~ Triangle B.
