Question

HELP! 9. 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. Be sure to include the formulas.

Answer 1

you just need to prove that the midpoints form segments that are perpendicular

Answer 2

find the slopes of each

Answer 3

each midsegment that is

Answer 4

find the slope of the line through (a,b) and (a, -b)
