Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180°.

Front

If one angle in a triangle measures 81° and another measures 37°, what is the measure of the third angle?

Back

62°

Front

What does CPCTC stand for?

Back

CPCTC stands for 'Corresponding parts of congruent triangles are congruent.'

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

If two angles of a triangle are 47° and 53°, what is the measure of the third angle?

Back

80°

Front

What is the relationship between the sides and angles of congruent triangles?

Back

In congruent triangles, corresponding sides are equal in length, and corresponding angles are equal in measure.

Front

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

Back

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

Front

What is the Side-Angle-Side (SAS) criterion for triangle congruence?

Back

If two sides of one triangle are equal to two sides of another triangle, and the included angle is equal, the triangles are congruent.

Front

What is the Side-Side-Side (SSS) criterion for triangle congruence?

Back

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

Front

If triangle ABC is congruent to triangle DEF, what can we say about their corresponding parts?

Back

The corresponding sides and angles of triangle ABC and triangle DEF are equal.
