    Use the distance formula for finding points on the xy-plane.

    Let d = distance.

    d = sqrt{(x2 - x1)^2 + (y2 - y1)^2}

    You must apply the above formula to find the distance between points A and B, B and C and A and C.

    So, you must apply the distance formula 3 times.

    Got it?

    If not, write back.
