A little league baseball diamond has 4 bases forming a square whose sides measure 20m each.The pitcher mound is 14 m from the home plate on a line joining home plate and second base.Find the distance from the pitcher's mound to 3rd base.

I don't get the bolded part of the problem. Can anyone explain to me, or show it in a diagram. Does it mean that the distance from pithcer's mound and2nd base is 14m in distance?
