U3 L3 DOL C2 S1 Angles

Which of the following accurately determines the measure of angle x and identifies the relationship of the angles?

• m∠x = 72° because alternate interior angles are congruent.

• m∠x = 72° because corresponding angles are congruent.

• m∠x = 72° because same side interior angles are supplementary.

• m∠x = 72° vertical angles are congruent.
