Types of Angles and Their Properties

Front

What is a Vertical Angle?

Back

Two angles across from each other on intersecting lines.

Front

What is a Supplementary Angle?

Back

Any two angles whose sum is 180 degrees.

Front

What is an Adjacent Angle?

Back

Two angles that are next to each other and share a common side.

Front

What is a Linear Pair?

Back

Two angles that are adjacent and supplementary (form a straight line).

Front

What is a Complementary Angle?

Back

Any two angles whose sum is 90 degrees.

Front

What are the properties of Vertical Angles?

Back

Vertical angles are equal in measure.

Front

How do you identify Supplementary Angles?

Back

Look for two angles that add up to 180 degrees.

Front

What is the relationship between Adjacent Angles?

Back

Adjacent angles share a common vertex and side.

Front

Can two angles be both Complementary and Supplementary?

Back

No, two angles cannot be both; they must sum to 90 or 180 degrees.

Front

What is the sum of angles in a Linear Pair?

Back

The sum is always 180 degrees.
