What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side; a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

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 are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

If angle 1 is 44 degrees, what is the measure of its complement?

Back

46 degrees (90 - 44 = 46).
