How?
In Quadrilateral WXYZ, is XY perpendicular to YZ? (1) WXY is a right angle (2) WZY is a right angle


For this to be true : LXYZ should be equal to 90

st 1:(1) WXY is a right angle

This states nothing abt LXYZ. Insufficient

st 2 : WZY is a right angle

Actually this nothing but the complementary of st 1. Again Insufficent as it does not give idea abt L XYZ
