WebThe angle bisectors of an isosceles triangle intersect at the incenter. The circle that is drawn with the incenter touches the three sides of the triangle internally. Each median divides the isosceles triangle into two equal triangles having the same area. The distance from the incenter to the centroid is less than one third the length of the longest median of the triangle. By Euler's theorem in geometry, the squared distance from the incenter I to the circumcenter O is given by where R and r are the circumradius and the inradius respectively; thus the circumradius is at leas…
