Question

Use ΔXYZ below to answer the question that follows: Triangle XYZ with sides YZ and YX intersected by line VW. Which fact is not used to prove that XYZ is similar to VYW? Angle Y is congruent to itself due to the reflexive property. Angles ZXY and WVY are congruent due to the Corresponding Angles Postulate. X, V, and Y are collinear points. XY is a transversal line passing VW and XZ.
