Find the lengths of all 4 sides: P(2,2) Q(1,-3) R(-4,2) S(-3,7)

 

Please hurry! Time is of the essence!

Just use the distance fromula, rarinstraw

 

For instance....PQ  = sqrt  [ (2 -1)^2 + (-3-2)^2 ]  = sqrt [1 + 25]   =  sqrt(26)  = RS

 

QR = sqrt [ (-1 - 4)^2 + (-3 -2)^2]  = sqrt [ 25 + 25]  = sqrt [50]  = 5sqrt(2)  = SP

 

 

 

cool cool cool
