Front

What is the relationship of angles that are on opposite sides of a transversal and inside the two lines?

Back

Alternate Interior Angles

Front

What is the relationship of angles that are on opposite sides of a transversal and outside the two lines?

Back

Alternate Exterior Angles

Front

What is the relationship of angles that are on the same side of the transversal and inside the two lines?

Back

Consecutive Interior Angles

Front

What is the relationship of angles that are on the same side of the transversal and outside the two lines?

Back

Consecutive Exterior Angles

Front

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

Back

Corresponding angles are equal.

Front

If angle 1 and angle 2 are alternate interior angles, what can be concluded if the lines are parallel?

Back

∠1 ≅ ∠2

Front

If angle 3 and angle 4 are consecutive interior angles, what can be concluded if the lines are parallel?

Back

∠3 + ∠4 = 180°

Front

What is the measure of angle 5 if it is a corresponding angle to angle 6 which measures 75°?

Back

Angle 5 measures 75°.
