Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

If angle B measures 120 degrees, what is the measure of angle Q if they are congruent?

Back

Angle Q also measures 120 degrees.

Front

What is the relationship between angles in a triangle?

Back

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

Front

What is the SAS criterion for triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What is the SSS criterion for triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to all three sides of another triangle.

Front

If m∠5 = 63°, what is the measure of ∠3 if they are supplementary?

Back

The measure of ∠3 is 117° because supplementary angles add up to 180°.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.
