One of several centers of a triangle can have the incenter, which is the point where the angle bisectors intersect. The incenter is also the center of the triangleÕs incircle-the largest circle that will fit inside the triangle and touch all three sides. The triangleÕs incenter is always inside the triangle.
Here, IÕm going to prove that the three angle bisectors of the internal angles of a triangle are concurrent.
