Construct a parallelogram ABCD. Extend the side [AB] such that BM = AB. Line (MC) intersects (AD) at N. The perpendicular to (BD) passing through A cuts (CD) at P. The perpendicular to (BD) passing through C cuts (AB) at Q. Let R be the foot of the perpendicular from D to (MN). Let S be the foot to the perpendicular from B to (MN).This feature of our site requires you to be a registered user. Click here to register, it is free! New to the site?
