Drag the orange dots on each vertex
to reshape the triangle. Note the way the three perpendicular bisectors always meet at a point - the circumcenter
One of several centers the triangle can have, the circumcenter is the point where the
bisectors of a triangle intersect.
The circumcenter is also the center of the triangle's circumcircle -
the circle that passes through all three of the triangle's vertices. As you reshape the triangle above, notice that the circumcenter may lie
outside the triangle.

... I have a small favor to ask. Over the years we have used advertising to support the site so it can remain free for everyone.
However, advertising revenue is falling and I have always hated the ads. So, would you go to Patreon and become a patron of the site?
When we reach the goal I will remove all advertising from the site.
It only takes a minute and any amount would be greatly appreciated.
Thank you for considering it! – John Page
