20. Complete the paragraph proof.
(5 points)
Given: 21 and 22 are supplementary, and 22 and 23 are supplementary.
Prove: 21 - 23
By definition of supplementary angles, mZ1 + m2 2 = (a) and m2 + m23 = (b).
Then, mZ1 + m2 = m 22+ m23 by the
Property (c). Subtract mZ2 from each
side. You get mZ1 = (d), or 21 - (e).
