What is the measure of ∠2 if it is given that ∠2 = 180° - ∠1 and ∠1 = 43°?

Back

∠2 = 180° - 43° = 137°.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180°.

Front

What is the definition of a midpoint in geometry?

Back

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the Hypotenuse-Leg (HL) theorem?

Front

How do you determine if two triangles are congruent?

Back

Two triangles are congruent if their corresponding sides and angles are equal.

Front

What is the definition of corresponding parts in congruent triangles?

Back

Corresponding parts are the sides and angles of two triangles that are in the same position relative to each triangle.
