He proof that UX ≅ SV is shown. Given: △STU an equilateral triangle ∠TXU ≅ ∠TVS Prove: UX ≅ SV Triangle T X V is shown. Point S is on side T X and point U is on side T V. A line is drawn from points S to U to form equilateral triangle T S U. Lines are drawn from point S to point V and from point U to point X and intersect at point W. What is the missing statement in the proof? Statement Reason 1. ∠TXU ≅ ∠TVS 1. Given 2. ∠STV ≅ ∠UTX 2. Reflex. Prop. 3. △STU is an equilateral triangle 3. Given 4. ST ≅ UT 4.
