Front

Which proportion can correctly prove △CDE ~ △CAB?

Back

Front

Which postulate or theorem is sufficient to prove the two triangles congruent?

Back

C) Hypotenuse-Leg

Front

What does it mean for two triangles to be similar?

Back

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

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 definition of congruent triangles?

Back

Triangles are congruent if all their corresponding sides and angles are equal.

Front

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

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.
