Question

e 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. Be sure to include the formulas.

Answer 1

Start again with a diagram. I can't give you the rest of the step as I'm about to step out. But hopefully you'll figure it out and/or someone else will help.
