Question

Which point is the circumcenter of the triangle?
A) E
B) G
C) F
D) D

Answer 1

Answer: Point D

Reason:

The circumcenter is found by intersecting the perpendicular bisectors of each segment of the triangle.

As you can see, the circumcenter is the center of the circumcircle. This special circle is the smallest possible that wraps the triangle so to speak. The vertices of the triangle are on the circle. The distances AD, BD and CD are all the same.
