Front

What is the definition of complementary angles?

Back

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

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 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 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.

Front

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

Back

60 degrees.

Front

What is the relationship between adjacent angles?

Back

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