Question

The vertices of a parallelogram pqrs are P(-1,-1) Q(-1,5) R(7,5) and S(7,-1). find the point where
the diagonals intersect​

Answer 1

Solution

for a parallelogram diagonals bisect each other...

so the the middle point of any diagonal is the point of intersection of the diagonals..

here the diagonals are PR & QS

now ...(taking any diagonal)

the middle point of PR

=(-1+7/2, -1+5/2)

=(3,2)
