[ATTACH=full]523[/ATTACH] Can you set this up for me to do?

the diagonals intersect at a midpoint , name it M, use midpoint formula and show that is the midpoint of each diagonal has same coordinates

Let M_1 = first midpoint. Let M_2 = second midpoint I need to show that M_1 = M_2. M_1 = [(a + b)/2, (c + 0)/2)] M_1 = [(a+b)/2, c/2)] M_2 = [(a + b + 0)/2, (c + 0)/2] M_2 = [(a + b)/2, c/2)] So, M_1 = M_2.

I will begin to post Calculus 1 questions on limits this weekend, Lord willing. Look for calculus questions in the Calculus Forum.
