Geometry please help!!!?

NetherCraft 0

The coordinates for a rhombus are given as (2a, 0), (0, 2b), (–2a, 0), and (0, –2b). Write a plan to prove that the midpoints of the sides of a rhombus determine a rectangle using coordinate geometry.

  • Side1: (2a,0) to (0, 2b)

    midpt: (a,b)

    Side2: (0, 2b) to (-2a, 0)

    midpoint: (-a,b)

    Side3: (-2a, 0) to (0, -2b)

    midpt: (-a, -b)

    Side4: (0, -2b) to (2a, 0)

    midpt: (a, -b)

    So the mid points form a rectangle from -a to a in X, and from -b to b in Y.

    Hope this helps!:)
