alternate angles, transversal

Front

What are alternate angles?

Back

Angles that are on opposite sides of a transversal and between two lines.

Front

Define transversal in geometry.

Back

A line that intersects two or more lines at different points.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

They are equal.

Front

If angle 1 = 27°, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 = 27°.

Front

If angle 3 = 67°, what is the measure of angle 5 if they are alternate interior angles?

Back

Angle 5 = 67°.

Front

What is the relationship between supplementary angles?

Back

They add up to 180°.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are equal.
