why don't u just use the distance formula?  read the coordinates of the endpoints of the diagnol you want then insert them into the distance formula.

anonymous · Answer

what are the coordinates 
thats what i get confused on

anonymous · Answer

is the answer 10.20

see the segment that joins A and C together?  you'll have to picture it in your head... that's a diagnol... a segment that joins opposite vertices together.  So BD is also a diagnol.  which one do you want to do?  AC or BD?

anonymous · Answer

ac
