The center of the circumscribed circle of the triangle
The center of the circle described near the triangle is the intersection point of the mid-perpendiculars to the sides of the triangle. In other words, the median perpendiculars intersect at one point. Its center is equidistant from all vertices, that is, it must be at the intersection point of the mid-perpendiculars to the sides of the triangle.
