The circumcenter of a triangle is the point where the perpendicular bisectors of its sides intersect. This point is equidistant from all three vertices of the triangle, making it the center of the circle that can be drawn around the triangle, known as the circumcircle. To find the circumcenter, you can draw the perpendicular bisectors of at least two sides of the triangle. The point where these bisectors meet is the circumcenter. This concept is important in geometry and is related to other topics such as circumcircle and triangle properties.
