Complementary, Supplementary, Adjacent, Vertical Angles

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What are adjacent angles?

Back

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

Front

What are vertical angles?

Back

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

Front

If one angle measures 30 degrees, what is the measure of its complementary angle?

Back

60 degrees.

Front

If one angle measures 120 degrees, what is the measure of its supplementary angle?

Back

60 degrees.

Front

What is the sum of the measures of two complementary angles?

Back

90 degrees.

Front

What is the sum of the measures of two supplementary angles?

Back

180 degrees.

Front

If two angles are adjacent and one measures 45 degrees, what is the maximum measure the other angle can have if they are supplementary?

Back

135 degrees.

Front

If two angles are vertical and one measures 75 degrees, what is the measure of the other angle?

Back

75 degrees.
