Question

In the adjoining figure, ABCD is a parallelogram and AP, CQ are perpendiculars from the vertices A, C
respectively on the diagonal BD. Show that
(i) ∆APB ≅ ∆CQD
(ii) AP = CQ.

Answer 1

in triangle apb and triangle cqd

AB=CD

angle p= angle q = 90 degree

angle CD = angle qba ( alternate angles)

therefore apb is congruent to cqd

ap =cq cpct
