In geometry, Euler's theorem states that the distance d between the circumcentre and incentre of a triangle can be expressed as D^{2}=R(R-2r) where R and r denote the circumradius and inradius respectively (the radii of the above two circles). The theorem is named for Leonhard Euler, who published it in 1767.
