The midpoint of the hypotenuse BC is (a%2F2, b%2F2). We can find the distance from each point to the midpoint and show that they are all equal.

A better way to prove this is to circumscribe a circle around ABC. Since BAC is a right angle, the hypotenuse BC is a diameter of the circle. We can draw the midpoint D and show that DA, DB, DC are all radii of the circle, hence they are equal.
