Question

Please help, studying for my test =) WXYZ is a trapezoid with vertices W(–1, 2), X(3, 2), Y(5, –1), and Z(–3, –1). Which is a line of symmetry with the correct justification?

a.) x=1 because it connects the midpoints of WX and ZY

b.) y=1/2 because it connects the midpoints of WX and XY

c.) Both choices A and B are lines of symmetry.

d.) ABCD has no lines of symmetry.

Thank you =)
