If ABCD is a quadrilateral whose diagonals AC and BD intersect at O, then

square ABCD is a parallelogram. The diagonals AC and BD intersect at point M . The length of seg AC , AB and AD is 24 , 22 and 34 respectively. Find the length of seg BD .

ABCD is a trapezium such that AB||CD. Its diagonals AC and BC intersect each other at O. Prove that (AO)/(OC) = (BO)/(OD)

if ABCD is a trapezium,AC and BD are the diagonals intersecting each other at point Q. then AC:BD=

ABCD is a parallelogram in which diagonals AC and BD intereset at O. If E, F, G and H are the mid points of AO, DO, CO and BO respectively, then the ratio of the perimeter of the quadrilateral EFGH to the perimeter of parallelogram ABCD is:

ABCD is a parallelogram whose diagonals AC and BD intersect at O. A line through O intersects AB at P and DC at Q. Prove that ar (Delta POA) =" ar "(Delta QOC) .

ABCD is a trapezium in which ABIDC and its diagonals intersect each other at the point 0. Show that (AO)/(BO)=(CO)/(DO)

In the adjoining figure, ABCD is a quadrilateral. Its diagonals AC and BD intersect at point 'O'. Prove that : (a) AB+BC+CD+DA lt 2(AC+BD) (b) AB+BC+CD+DA gt (AC+BD)
