Complementary, Supplementary, Vertical and Adjacent angles

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are adjacent angles?

Back

Two angles that share a common side and a common vertex.

Front

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

Back

60 degrees.

Front

If two angles are supplementary and one measures 70 degrees, what is the measure of the other angle?

Back

110 degrees.

Front

If two vertical angles are equal and one measures 45 degrees, what is the measure of the other angle?

Back

45 degrees.

Front

If two adjacent angles form a straight line, what is the sum of their measures?

Back

180 degrees.

Front

What is the measure of the missing angle if one angle is 89 degrees and they are complementary?

Back

1 degree.

Front

If angle x is 58 degrees and angle y is its supplementary angle, what is the measure of angle y?

Back

122 degrees.
