The Circumcentre is the point of intersection of the three perpendicular bisectors of the sides of a triangle.  The circumcentre is the centre of a circle that passes through ALL the vertices of a triangle.  Common use in a word problem is to find a point that is equidistant from three points.  The three points become vertices of a triangle and then you're off to the races!
In this lesson I do two full examples; one where the circumcentre is INSIDE the triangle and one where it is OUTSIDE the triangle.
