Let ABCDE be a convex pentagon such that the
triangles ABC, ACD, and ADE are similar.
The diagonals BD and CE intersect in point P.

Prove that the ray AP bisects side CD.

Thank you for pointing out the typo which I have now corrected (although in fairness to myself I gave the coordinates as well). But I still need to know what is substantively wrong with the construction I gave i.e. how it differs from the construction you intended.
