Circumcenter Theorem

the perpendicular bisectors of a triangle intersect at a point called the circumcenter that is equidistant from the vertices of the triangle

The Circumcenter Theorem states that the perpendicular bisectors of the sides of a triangle intersect at a single point known as the circumcenter.

In other words, the circumcenter is the point of intersection of the perpendicular bisectors of a triangle’s sides. This point is equidistant from the three vertices of the triangle.

The circumcenter also plays an important role in determining the properties of the circumcircle, which is the circle passing through all three vertices of the triangle. The circumradius, which is the radius of this circumcircle, can be found by taking the distance between the circumcenter and any of the vertices of the triangle.

The Circumcenter Theorem can be proven using basic geometry. Suppose we have a triangle ABC with points D, E, and F on the sides BC, AC, and AB respectively. Let O be the point where the perpendicular bisectors of DE and EF intersect. By definition, we know that OD = OE and OF = OE since O is equidistant from the three points D, E, and F.

Therefore, we can conclude that the triangle ODF and ODE are congruent by the Side-Side-Side (SSS) criterion, which means that More Answers: The Power Of The Converse Of Angle Bisector Theorem In Geometry Proofs
