Complete the paragraph proof.

Given: ∠1 and ∠2 are supplementary, and ∠2 and ∠3 are supplementary.

Prove: ∠1 ≅ ∠3

Angle 1 is acute, angle 2 is obtuse, and angle three is acute.

By definition of supplementary angles, m∠1 + m∠2 = _____ (a) and m∠2 + m∠3 = _____ (b). Then, m∠1 + m∠2 = m∠2 + m∠3 by the __________ (c). Subtract m∠2 from each side. You get m∠1 = ______ (d), or ∠1 ≅ _____ (e).
