The figure below shows some steps performed to circumscribe a circle about triangle ABC using only a compass and straightedge.

Which statement about the radius of the circumscribed circle must be true?

It is the same as the altitude of side AC.

It is the same as the length from point O to any of the vertices A, B, or C.

It is the same as the length from point O to any of the sides of the triangle.

It is the same as the median of side AC.

May someone please help me?

Do you know what the definition of this circle is?

anonymous · Answer

um, a  point with points in all directions from it that are the same distance from the center point?

anonymous · Answer

The circumcircle is the circle which includes all three vertices of the triangle on the circumference of the circle.  That means each point is the same distance away from the origin of the circle.
