Do I need to use the slop formula first to prove the figure is a parallelogram?
OpenStudy (nikato):
Yes. Find the slope of AC and BD. If they are negative recipricol of each other, you have proved the diagonals are perpendicular which proves that it's a rhombus
OpenStudy (nikato):
I think it's given in the problem that its a paralleogram, so you don't have to prove that
OpenStudy (anonymous):
Oh, that makes sense thanks!
