Types of Angle Pairs

Front

What is an adjacent angle pair?

Back

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

Front

Define vertical angles.

Back

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

Front

What is the sum of the angles in a straight line?

Back

The sum of the angles on a straight line is 180 degrees.

Front

What are 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

How do you identify vertical angles in a diagram?

Back

Vertical angles can be identified as the angles that are opposite each other at the intersection of two lines.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles can be complementary or supplementary, depending on their measures.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the relationship between angles formed by parallel lines and a transversal?

Back

When a transversal crosses parallel lines, it creates corresponding angles, alternate interior angles, and alternate exterior angles, which have specific relationships.

Front

What is the definition of a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.
