[Christian S.]

Can you show me how to solve these problems?
1. In an isosceles triangle,ABC, when AM and CM are the angle bisectors of angle BAC, what is the measure of angle AMC?

2. In the figure above, the square is inscribed in the circle. What is the degree measure of arc ST?

#1 How is it that you have two bisectors of same angle which meet at a point other than the apex? Is that problem posted correctly?

#2 Where is the figure?
