We are now going to take a look at another triangle center called the incenter. The angle bisectors of the angles of a triangle are concurrent they intersect in one common point. The point of concurrency of the angle bisectors is called the incenter of the triangle. The point of concurrency is always located in the interior of the triangle. Locate the incenter through construction : We have seen how to construct angle bisectors of a triangle. Simply construct the angle bisectors of the three angles of the triangle.

Brian was a geometry teacher through the Teach for America program and started the geometry program at his school. To unlock all 5, videos, start your free trial. The point of concurrency of the three angle bisectors of a triangle is the incenter. It is the center of the circle that can be inscribed in the triangle, making the incenter equidistant from the three sides of the triangle. To construct the incenter, first construct the three angle bisectors; the point where they all intersect is the incenter. The incenter is always located within the triangle. One of the four special types of points of concurrency inside a triangle is the incenter.

Construction of incenter of a triangle :. Even though students know what is incenter, many students do not know, how to construct incenter. Key Concept - In center. To construct a incenter, we must need the following instruments. Let us see, how to construct incenter through the following example.

No other point has this quality. Incenters, like centroids, are always inside their triangles. The above figure shows two triangles with their incenters and inscribed circles, or incircles circles drawn inside the triangles so the circles barely touch the sides of each triangle. The incenters are the centers of the incircles. The circumcenters are the centers of the circumcircles. You can see in the above figure that, unlike centroids and incenters, a circumcenter is sometimes outside the triangle. The circumcenter is.
