Question

Proof:
If WXYZ is a parallelogram, (angle)W is congruent with (angle)X, and M is the midpoint for WX.

Write a paragraph proof to prove that ZMY is an Isosceles triangle.

Lines; one segment lines.
W->M->X)(X->Y)(Y->Z)(Z->W)( Z->M
And Y->M.
)( = a change of direction.
Also (angle)W and X are 90 degrees angles.
