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.
In a right triangle, the orthocenter is the polygon vertex of the right angle. When the vertices of a triangle are combined with its orthocenter, any one of the points is the orthocenter of the other three, as first noted by Carnot (Wells 1991). These four points therefore form an orthocentric system. The circumcenter and orthocenter are isogonal conjugates. The orthocenter lies on the Euler line.
