amorfide · Answer

you would use the distance of two points

steve816 · Answer

Nope, distance formula is not needed.

it would still be a viable method though

Okay well there is 4 points how do I figure out which two points I have to use? Do I use distance formula for each pair?

steve816 · Answer

If the slope between the 2 sets of two of the points are the same, than it would be a parallelogram.

lmao After looking at the picture I realized  I thought distance formula was slope formula lol sorry

narissa · Answer

AB=1/2 BC=-3/2 CD=-1/2 DA=1/2

steve816 · Answer

AB and DA have the same slope! That means it indeed is a parallelogram :)
