Back

Collinear points are points that lie on the same straight line.

Front

What are complementary angles?

Back

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

Front

If m∠3 = 7x – 13 and m∠6 = 2x + 37, how do you find m∠4?

Back

Set m∠3 + m∠4 = 180° and solve for x, then substitute back to find m∠4.

Front

What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How do you prove that two angles are complementary?

Back

Show that the sum of their measures equals 90 degrees.

Front

What is the Subtraction Property of Equality?

Back

If a = b, then a - c = b - c for any c.

Front

What is the Reflexive Property?

Back

A quantity is equal to itself; for example, a = a.

Front

What is the Transitive Property?

Back

If a = b and b = c, then a = c.
