Angle Pairs

Front

What are Linear Pairs?

Back

Linear pairs are two adjacent angles that form a straight line. The sum of their measures is 180 degrees.

Front

Define 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 Vertical Angles?

Back

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

Front

What does it mean for angles to be Adjacent?

Back

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

Front

If one angle measures 22 degrees, what is the measure of its supplementary angle?

Back

158 degrees.

Front

If two angles are complementary and one measures 30 degrees, what is the measure of the other angle?

Back

60 degrees.

Front

What is the relationship between a linear pair of angles?

Back

A linear pair of angles are supplementary, meaning their measures add up to 180 degrees.

Front

How can you identify complementary angles in a diagram?

Back

Look for two angles that together form a right angle (90 degrees).

Front

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

Back

The sum is always 180 degrees.
