We start with a triangle ABC.
1. Find the bisector of one of the triangle sides. Any one will do.
See Constructing the Perpendicular Bisector of a Line Segment for detailed instructions.
|2. Repeat for the another side. Any one will do.|
|3. Mark the point where these two perpendiculars intersect as point O.|
|(Optional step) Repeat for the third side. This will convince you that the three bisectors do, in fact, intersect at a single point. But two are enough to find that point.|
Done The point O is the circumcenter of the triangle ABC.
Note: This point may be outside the triangle. This is normal.
