Transversal angle pairs

Front

What are vertical angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are the angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Alternate interior angles are the pairs of angles on opposite sides of the transversal but inside the two parallel lines. They are equal in measure.

Front

What are linear angles?

Back

Linear angles are adjacent angles that form a straight line. Their measures add up to 180 degrees.

Front

If angle P measures 60 degrees, what is the measure of angle C?

Back

120 degrees (since angle C is the supplementary angle to angle P).

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are the pairs of angles on opposite sides of the transversal but outside the two parallel lines. They are equal in measure.

Front

How do you identify vertical angles in a diagram?

Back

Vertical angles are formed by two intersecting lines and are located opposite each other.

Front

What is the sum of the measures of linear angles?

Back

The sum of the measures of linear angles is always 180 degrees.

Front

If two angles are corresponding angles, what can you conclude about their measures?

Back

If two angles are corresponding angles, they are equal in measure.
