In Minimal area, we were asked to find the property of a line which minimized the area of the triangle it completed. It turned out the given point was the midpoint of the third side. In this problem, I am asking for a ruler and compass construction of that line, given the original angle and point.

(In reply to re: Solution by Jer)

The construction was devised to satisfy that last equation (which came from my proof for the "Minimal area" problem).

I edited my construction to specify which ray point A (and therefore point B) was on.

Does anybody know how to get rid of the blank line that occurs when you edit a problem solution?
