Distance between circumcenter and orthocenter ?

The distance between circum centre and orthocenter of the triangle whose vertices are (0,0),(6,8) and (-4,3) is

A triangle are (6,0).(0,6) and (6,6). If distance between circumcentre and orthocenter and distance between circumcentre and centroid are lambda and u unit respectively,then (lambda,u) lies on:

The distance between the circumcentre and orthocenter of a Delta ABC is R sqrt(1-lambda cos A*cos B*cos C), then lambda=

Distance Between Circumcenter and incenter

Prove that the distance between the circumcenter and the incenter of triangle ABC is sqrt(R^(2)-2Rr)

The distance between the circumcenter and the orthocentre of the triangle whose vertices are (0,0),(6,8), and (-4,3) is L. Then the value of (2)/(sqrt(5))L is
