Euclid: The Game - Level 15

Goal: Construct the incircle of the triangle. An incircle is a circle fully contained in a triangle and is tangent to all three sides.

Show hint:   Once you have identified the center of the incircle, your eyes can trick you into choosing the wrong radius. What must be true about a tangent to a circle and the radius to that point of tangency?
