ANGEL RELATIONSHIPS & SOLVING EQUATIONS

Front

What are vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines intersect. They are always congruent (equal measures).

Front

What is the sum of two complementary angles?

Back

The sum of two complementary angles is 90 degrees.

Front

What is the sum of two supplementary angles?

Back

The sum of two supplementary angles is 180 degrees.

Front

If one angle is 60°, what is the complementary angle?

Back

The complementary angle is 30°.

Front

If two angles are supplementary and one angle is 70°, what is the other angle?

Back

The other angle is 110°.

Front

What is an example of a pair of supplementary angles?

Back

Example: 120° and 60°.

Front

What is an example of a pair of complementary angles?

Back

Example: 45° and 45°.

Front

If angle A is 25° and angle B is complementary to angle A, what is angle B?

Back

Angle B is 65°.

Front

If angle C is 90°, what type of angle is it?

Back

Angle C is a right angle.

Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex.
