• B. The sum of the measures of a pair of corresponding angles is 180°
• C. The sum of the measures of a pair of interior angles on the same side of the transversal is 180°
• D. The sum of the measures of a pair of vertically opposite angles is 180°

Answer 1

Answer:

C. The sum of the measures of a pair of interior angles on the same side of the transversal is 180°
