join the point up like a triangle eg bay view to mountain view then mountain view to hill view.
Lets take bay view to mountain view as an example. Go along halfway and draw a straight line from the halfway point all the way through. (it should be a right angle on both sides) and basically draw the line so it cuts between the triangle. then repeat for all three sides. The lines should join up at a point and that is the equidistant point... if not there will be a small gap. but s in the middle
