Create a  Rotation Matrix for 3 point x,y vectors

I have an object that I need to rotate/reposition. I want to use a rotation matrix but because the x,y position of the object is determined by 6 values ( lets say x = 435, 435, 510 and y= 500 ,456, 543).

How do I use a rotation matrix for this? ( The object is a triangle) , and I want it to rotate counterclockwise 90 degrees.

    Thank you this was rather helpful, this issue for me is that the vectors are non-zero numbers.
