1. The problem statement, all variables and given/known data This is part from a larger construction, but I realized if i can construct this, i can do the larger construction. All ofcourse with ruler and compass. I have been given an angle with its bisector and a point on that bisector. I have to construct a circle trough that point (A), such that the lines from the angle are tangent lines to the circle. 3. The attempt at a solution I have to find a point M and B such that AM = BM, and than i can construct the circle. But i have no idea how to do this.
