Question from Nazrul, a teacher:

The circumcentre, centroid and orthocentre of a triangle is
given. The distance between circumcentre and orthocentre is also
given.
How can I draw the circle?
Please Help me.

Nazrul,

In general you need three independent pieces of information to reproduce a triangle. You have been given only two: the centroid lies on the segment joining the orthocenter to the circumcenter, lying 2/3 of the way from the orthocenter to the circumcenter. You are free to choose a vertex of the triangle to lie almost anywhere in the plane.
