    Does it work for a square?

    In general, no, think about a simple equalateral triangle.

    I'm assuming that says 35 degrees?

    Can you see how I've filled in the other angles? They're all the same, since that horizontal line at the top is parallel to the horizontal line on the bottom.

    In answer to your question, that interior angle will indeed be the same as the exterior angle they gave you, in this case.

    I learned them as "vertically opposite angles" and the "Z-rule", I don't know what your teacher might have called them.

    Great! All the angles should be 35 degrees then! (except the interior one at the top of the triangle, of course)

    WXYZ is a quadrilateral in which W = 108 , X = 88 , Y = 57 and WXY = 31.Calculate WZX and XZY.

    Listen, I have to go study myself now. Can you copy and paste that into a new question? That way somebody else will be able to help. You should make it clear whether W, X, Y and WXY are - are they lenghts, angles etc? I have to go now though, so make sure you create a new question, so somebody else can answer it.
