Given: ∠TUW ≅ ∠SRW; RS ≅ TU Prove: ∠RST ≅ ∠UTS Triangles R W S and U W T connect at point W. A line is drawn to connect points S and T. Another line is drawn from point R to point V and down to point U. Sides S R and T U are congruent. Angles S R W and W U T are congruent. Complete the paragraph proof: It is given that ∠TUW ≅ ∠SRW and RS ≅ TU. Because ∠RWS and ∠UWT are vertical angles and vertical angles are congruent, ∠RWS ≅ ∠UWT. Then, by AAS, △TUW ≅ △SRW. Because CPCTC, SW ≅ TW and WU ≅ RW. Because of the definition of congruence, SW = TW and WU = RW. If we add those equations together, SW WU = TW RW. Because of segment addition, SW WU = SU and TW RW = TR. Then by substitution, SU = TR. If segments are equal, then they are congruent, so SU ≅ TR. Because of , △TRS ≅ △SUT, and because of , ∠RST ≅ ∠UTS.
