hi peoples of math help forum! -waves-

i hope this belongs in the geometry board, as my teacher said there are multiple ways to solve it. this is the question that has be stumped:

Points D and E are the endpoints of one of the sides of a square. If the coordinates of the midpoint of DE are (4.5, 16) and the coordinates of D are (2, 16), what are the coordinates of the vertices of the square.

thanks
