P,Q are the mid-points of the non-parallel sides BC and AD of a trapezium ABCDShow that Delta APD=Delta CQB

E and F are the mid points of non-parallel sides AD and BC respectively of a trapezium prove that EF||AB.

If D is the mid-point of the side BC of triangle ABC and AD is perpendicular to AC, then

If D is the mid-point of the side BC of a triangle ABC, prove that vec AB+vec AC=2vec AD .

If P,Q and R are the mid-point of the side BC,CA and AB of a triangle and AD is the perpendicular form A and BC, prove that P,Q and D are concylic.

If D is the mid-point of side BC of a triangle ABC and AD is perpendicular to AC, then
