Two lines are parallel, and a co-interior angle is 110°. What is the other co-interior angle?

70°

110°

80°

250°

Two parallel lines have alternate angles 4x and 60°. Find x.

x = 60

x = 15

x = 240

x = 16

Two parallel lines have co-interior angles (3x − 20)° and (x + 40)°. Find x.

x = 30

x = 50

x = 40

x = 20

If the corresponding angles are not equal, are the lines parallel?

Yes, because the angles are not equal

Yes, because the angles are alternate

No, because corresponding angles are always equal

No, because equal corresponding angles are required for parallel lines
