Question

Find the coordinates of the intersection of the diagonals of parallelogram WXYZ with the following vertices: W (-1, 7), X (8, 7), Y (6, -2) and Z (-3, -2)

Answer 1

(1.5, -2)

(7, 2.5)

(2.5, 2.5)

(3.5, 7)

Answer 2

find slopes of all possible combinations
WX,WY,WZ,XY,XZ,YZ.
of these , two sets turn out to be identicle slopes
which means they are the four sides of the parallelogram.
so the other two sides represent diagonal.
find the mid point of one of teh sides to get the point of intersection

Answer 3

is the answer b?
