11.30 Triangle Similarity Practice

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What does it mean for angles in similar figures?

Back

All angles in similar figures are congruent.

Front

What is the symbol for congruence?

Back

The symbol for congruence is '≅'.

Front

What is the relationship between the sides of similar triangles?

Back

The ratios of the lengths of corresponding sides are equal.

Front

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

Back

Their corresponding angles are equal.

Front

How do you determine if two triangles are similar?

Back

By using the Angle-Angle (AA) similarity postulate, Side-Angle-Side (SAS) similarity theorem, or Side-Side-Side (SSS) similarity theorem.

Front

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

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

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

Back

If an angle of one triangle is equal to an angle of another triangle and the sides including these angles are in proportion, then the triangles are similar.

Front

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

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

Complete the congruence statement: If triangle A is congruent to triangle B, then...

Back

...the corresponding sides and angles of triangle A and triangle B are equal.
