Triangle Incenter
The incenter of a triangle is the center of its inscribed circle. Because of this, it is equidistant from all three sides, although not necessarily at the middle of each side. It is found at the intersection point of the angle bisectors. Unlike the circumcenter, the incenter will always be found inside the triangle. A circle formed with this point as its center will be tangent to all three sides. Find out more at http://en.wikipedia.org/wiki/Incenter.
