The incenter is the one point in the triangle whose distances to the sides are equal. (See picture) 1  If the triangle is obtuse, such as the one on pictured below on the left, then the incenter is located in the triangle's interior.  If the triangle is acute, then the incenter is also located in the triangle's interior.
All triangles have an incenter, and it always lies inside the triangle. One way to find the incenter makes use of the property that the incenter is the intersection of the three angle bisectors, using coordinate geometry to determine the incenter's location. Unfortunately, this is often computationally tedious.
