Geometry :)

posted by .

Use coordinate geometry to prove that the quadrilateral formed by connecting the midpoints of a kite is a rectangle.

I have no Idea how to do this problem, so if anyone could help I would be very greatfull. :)

    Let the diagonals intersect at (0,0)
    Then let the vertices of the kite be at

    (-2a,0),(2a,0) and (0,2b),(0,-2c)

    The midpoints of the sides are thus at

    Those are obviously the vertices of a rectangle.

    Thanks :)
