Using the information in the diagram, state the free fact needed and the theorem usedto prove that WZI WZY.ZFree fact: Select)Congruence Theorem: (Select)


WX = WZ (Given)
WY = WY (Reflexive property of equality)
angle XWY = angle YWZ
Hence triangle WXY = triangle WZY
SAS (Two sides and an included angle)
