Points (1, -5) and (11, 7) are the opposite vertices of a parallelogram. What are the coordinates of the point where the diagonals of the parallelogram intersect?
The diagonals bisect each other...therefore......the point where the diagonals intersect must be the mid-point of these two coordinates =
( [ 1 + 11 ] / 2, [ -5 + 7 ] / 2 ) = ( 12 / 2, 2 / 2 ) = (6, 1 )
Thank you again, Chris
