Complementary and Supplementary Vertical and Adjacent Angles

Front

What is the definition of complementary angles?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is the definition of supplementary angles?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

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 adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

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

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

Can two angles be both complementary and supplementary?

Back

No, two angles cannot be both complementary and supplementary at the same time.

Front

What is the relationship between complementary angles and right angles?

Back

Complementary angles add up to form a right angle (90 degrees).

Front

What is the relationship between supplementary angles and straight angles?

Back

Supplementary angles add up to form a straight angle (180 degrees).

Front

If angle A is 45 degrees, what is the measure of angle B if A and B are complementary?

Back

Angle B is 45 degrees.
