Question

in a trapezium abcd ab is parallel to dc x is the midpoint of diagonal ac and y is the midpoint of bd if ac= 8 and bd=3 then find cd

Answer 1

Answer:

given a trapezium abcd with parallel sides AB and CD let O be the intersection of the siagonals AC and BD. If the ratio r = AB/CD then the diagonals are divided by this same ratio :

AO/CO= BO/DO =r
