A circumcenter is a point of concurrency of the perpendicular bisectors of a triangle.

HB

Practice makes perfect

It is given that D is a circumcenter of the triangle △ ABC. Let's review that a circumcenter is a point of concurrency of the perpendicular bisectors of a triangle.

Thus, DH is a perpendicular bisector of AB. A bisector of the segment intersects it in its midpoint, so H is a midpoint of the segment AB. Therefore, AH and HB are congruent segments.
