Parallel Lines cut by a transversal Review

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal. They are equal when the lines are parallel.

Front

What is the sum of the interior angles on the same side of the transversal?

Back

The sum is 180°.

Front

If angle TLS = (x + 13)° and angle LMO = (2x - 4)°, what is the relationship between these angles if the lines are parallel?

Back

Angle TLS + Angle LMO = 180°.

Front

Solve for x: angle 1 = (3x + 10)° and angle 2 = (2x + 30)°, if angle 1 and angle 2 are supplementary.

Back

x = 20.
