Front

The angle relationship shown is -

Back

Complementary angles are two angles that add up to 90 degrees.

Front

If m∠1 = 30°, then m∠3 = ?

Back

If m∠1 = 30°, then m∠3 = 30° (if they are vertical angles).

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are adjacent angles?

Back

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

Front

What is the sum of complementary angles?

Back

The sum of complementary angles is 90 degrees.

Front

What is the sum of supplementary angles?

Back

The sum of supplementary angles is 180 degrees.

Front

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

Back

The other angle measures 110° (180° - 70° = 110°).
