ANSWER THIS ASAP In the figure below, OPN is a reflected image of MPN
Anne states that reflections preserve side lengths, so PN = PN, PM = PO, and MN = ON therefore the triangles are congruent. Tim states that reflections preserve angle measures, so MPN = ONP and PMN = PON, therefore the triangles are congruent . WHO IS CORRECT?

A) Neither Anne nor Tim
B) both Anne and Tim
C) only Anne
D) only Tim

Here is their argument. given the obtuse angle x, we make a quadrilateral abcd with ∠dab = x, and ∠abc = 90◦, and ad = bc. say the perpendicular bisector to dc meets the perpendicular bisector to ab at p. then pa = pb and pc = pd. so the triangles pad and pbc have equal sides and are congruent. thus ∠pad = ∠pbc. but pab is isosceles, hence ∠pab = ∠pba. subtracting, gives x = ∠pad−∠pab = ∠pbc −∠pba = 90◦. this is a preposterous conclusion – just where is the mistake in the "proof" and why does the argument break down there?
