Angle Relations

Identify the vertical angle for an angle of 120 degrees.

• 90 degrees

• 180 degrees

• 120 degrees

• 60 degrees

If two angles are supplementary and one angle measures 60 degrees, what is the measure of the other angle?

• 90 degrees

• 120 degrees

• 150 degrees

• 30 degrees

What are the corresponding angles for an angle of 45 degrees?

• 360 degrees

• 45 degrees

• 90 degrees

• 180 degrees

Define alternate interior angles.

• Angles that are on the same side of the transversal line and outside the parallel lines

• Angles that are on the opposite sides of the transversal line and outside the parallel lines

• Angles that are on the same side of the transversal line and inside the parallel lines

• A pair of angles that are on the opposite sides of the transversal line and inside the parallel lines, equal in measure.

Calculate the missing angle if two consecutive interior angles are 80 degrees and 100 degrees.

• 120

• 0

• 45

• 60

Explain the concept of alternate exterior angles.

• Alternate exterior angles are congruent.

• Alternate exterior angles are acute.

• Alternate exterior angles are parallel.

• Alternate exterior angles are supplementary.
