Question

I need guidance through a question, please help! Medal!

Answer 1

Do I need to use the slop formula first to prove the figure is a parallelogram?

Answer 2

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

Answer 3

I think it's given in the problem that its a paralleogram, so you don't have to prove that

Answer 4

Oh, that makes sense thanks!

Answer 5

No problem
