Complementary,Supplementary, 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 complementary angles?

Back

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

Front

What are supplementary angles?

Back

Supplementary angles are two angles that add up to 180°.

Front

If one angle measures 30°, what is its complement?

Back

60°

Front

If two angles are supplementary and one measures 110°, what is the measure of the other angle?

Back

70°

Front

What is the equation to find the complement of an angle x?

Back

90 - x = complement angle.

Front

What is the equation to find the supplement of an angle x?

Back

180 - x = supplement angle.

Front

If ∠1 and ∠3 are vertical angles, what can we say about their measures?

Back

∠1 = ∠3.

Front

If two angles are adjacent and one measures 45°, what is the measure of the other angle if they are complementary?

Back

45°.

Front

What is the sum of the measures of complementary angles?

Back

90°.
