Question

The circumradius of a triangle is:

Options

• The perimeter of the circumcircle

• The distance from the circumcenter to any vertex

• The distance from the circumcenter to any side

• Half the perimeter of the triangle

Answer 1

The distance from the circumcenter to any vertex

Explanation:

The circumradius (R) is the radius of the circumcircle, measured as the distance from the circumcenter to any of the three vertices. Since the circumcenter is equidistant from all vertices, this distance is the same for all three.
