PLEASE HELP ME ASAP!!

the vertices of a square are a(-2 4), b(4,4), c(4,-2), d(-2,-2). the diagonals of the square intersect at their midpoints. what are the coordinates of the midpoint where the diagonals intersect

We have to find midpoint M of the diagonal AC (or BD, there is no difference) so:

[tex]M=\left(\dfrac{x_A+x_C}{2},\dfrac{y_A+y_C}{2}\right)=\left(\dfrac{-2+4}{2},\dfrac{4+(-2)}{2}\right)=\left(\dfrac{2}{2},\dfrac{2}{2}\right)=\\\\\\=\boxed{(1,1)}[/tex]
