Given: ∠XWU ≅ ∠ZVT; ∠ZTV ≅ ∠XUW; TU ≅ VW Triangles Z V T and X W U overlap and intersect at point Y. Angles Z T U and W U W are congruent. Angles Z V T and X W U are congruent. Lines segment T U and V W are congruent. A line is drawn through point Y to point S on side X W and to point R on side Z T. Another line connects points Z and X.
