The properties of the circumcenter of a triangle are as follows:

1. The circumcenter is the center of the circumcircle, which is the circle that passes through all three vertices of the triangle.
2. The circumcenter is equidistant from all three vertices of the triangle.
3. The circumcenter lies on the perpendicular bisectors of the sides of the triangle.
4. The circumcenter is the point of concurrency of the perpendicular bisectors of the sides of the triangle.
5. The distance from the circumcenter to any side of the triangle is equal to the radius of the circumcircle.
