B 28. Given: AB BC Prove: <1* <4 Assume Since <1 and <2, as well as <3 and <4 are linear pairs, they are supplementary,
B 28. Given: AB BC Prove: <1* <4 Assume Since <1 and <2, as well as <3 and <4 are linear pairs, they are supplementary, Since <3 and <3 are supplements of congruent angles, then It follows that However, this contradicts the given information that Therefore the assumption and we can conclude that
