2 1 3 Move words to the blanks and equations to the boxes to prove that vertical angles 21 and 3 are congruent. Because linear pairs of angles are and Because angles that are to the same angle are It can be concluded that 21 23. congruent supplementary mzl + m2 = 180° m21 + m23 = 180° m 2 + m23 = 180°

The reflexive property of congruence lets you say that ∠pqr ≅
