The applet below shows a circle circumscribed about triangle ABC with circumcenter at J.
Recall that the circumcenter is the point of concurrency of perpendicular bisector of all three sides of a triangle.
Drag any of the vertices of triangle ABC.
When do you observe point J to be inside or outside the triangle, or lying on a side of the triangle?
Write down all other observations you may have.
