What are vertical angles?

Back

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

If m∠A = 40°, what is m∠B if A and B are complementary?

Back

m∠B = 50° (because 90° - 40° = 50°).

If m∠C = 120°, what is m∠D if C and D are supplementary?

Back

m∠D = 60° (because 180° - 120° = 60°).

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line, adding up to 180 degrees.

If two angles are vertical, what can we say about their measures?

Back

The measures of vertical angles are equal.

If m∠1 = 30°, what is m∠2 if ∠1 and ∠2 are a linear pair?

Back

m∠2 = 150° (because 180° - 30° = 150°).
