What is a circumcenter?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect. It is equidistant from all three vertices of the triangle.

How do you find the circumcenter of a triangle?

Back

To find the circumcenter, construct the perpendicular bisectors of at least two sides of the triangle. The point where they intersect is the circumcenter.

What is the relationship between the circumcenter and the circumcircle?

Back

The circumcenter is the center of the circumcircle, which is the circle that passes through all three vertices of the triangle.

If D is the circumcenter of triangle ABC, what can be said about the distances from D to A, B, and C?

Back

The distances from D to A, B, and C are all equal, meaning DA = DB = DC.

What is the Perpendicular Bisector Theorem?

Back

The Perpendicular Bisector Theorem states that any point on the perpendicular bisector of a segment is equidistant from the endpoints of that segment.

How can the Perpendicular Bisector Theorem be applied to find unknown lengths?

Back

By using the theorem, if a point lies on the perpendicular bisector, you can set the distances to the endpoints equal to each other to solve for unknown lengths.
