Front

What is a rectangle?

Back

A rectangle is a quadrilateral with all angles congruent (each measuring 90°) and opposite sides that are equal in length.

Front

What is the complement of an angle?

Back

The complement of an angle is what, when added to that angle, equals 90°. For example, the complement of 30° is 60°.

Front

What is the supplement of an angle?

Back

The supplement of an angle is what, when added to that angle, equals 180°. For example, if the supplement of an angle is 65°, then the angle measures 115°.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside two parallel lines. They are congruent.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that are on the same side of a transversal and inside two parallel lines. They are supplementary.
