The vertices of a triangle are P(-3,1,2), Q(1,-3,-1) and R(3,-1,-1)
-Verify that it is a right angled
-Determine the area
-Determine the perimeter
-What are the coordinates of S(x,y,z) such that PQRS is a rectangle
I'm not sure how to start to go about solving this problem. Could someone give me a nudge forward? =/
Thank you.
