Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If one angle is twice as large as the other, how do you express this relationship mathematically?

Back

Let the smaller angle be x. Then the larger angle is 2x. The equation is x + 2x = 90.
