    I can do this vectors and higher maths, but I guess you have not learnt that. You should graph the points, maybe it helps. I get a pen and paper too

    I thought about it and have a way of solving it. If they are perpendicular that means that the slope of the two line are the same just with opposite signs. Do you know how to get the slope of the line that connects RS?
