Unit 7 Review #3

Front

What is the Angle-Angle (AA) similarity criterion?

Back

The AA similarity criterion states that if two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar.

Front

What does it mean for triangles to be similar?

Back

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

Front

What is the Side-Angle-Side (SAS) similarity criterion?

Back

The SAS similarity criterion states that if one angle of a triangle is congruent to one angle of another triangle and the sides including those angles are in proportion, then the triangles are similar.

Front

What is the Side-Side-Side (SSS) similarity criterion?

Back

The SSS similarity criterion states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

How can you determine if two triangles are not similar?

Back

Two triangles are not similar if their corresponding angles are not equal or their corresponding sides are not in proportion.

Front

What is the value of X if 2X + 4 = 8?

Back

X = 2.

Front

If ∠U ≅ ∠F, what can be concluded about these angles?

Back

The angles are congruent, meaning they have the same measure.

Front

What is the relationship between similar triangles and their areas?

Back

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

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

If triangle A is similar to triangle B, what can be said about their corresponding sides?

Back

The lengths of the corresponding sides of triangle A and triangle B are in proportion.
