3.1 Angle Pairs

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Define vertical angles.

Back

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

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines.

Front

What is the relationship between same side interior angles?

Back

Same side interior angles are supplementary when two parallel lines are cut by a transversal.

Front

Identify the corresponding angle to

Back

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is the classification of ∠6 and ∠7 if they are opposite angles formed by two intersecting lines?

Back

They are vertical angles.

Front

What are same side exterior angles?

Back

Angles that are on the same side of the transversal and outside the two lines.
