In the circle shown, AB is tangent to circle o at point and OC is a radius Which relationship is true?

A.

Step-by-step explanation:

According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.

Given that is a tangent of the circle O, at a point C, and is a radius, therefore, it follows that:

.

This means the radius of the circle is perpendicular to the tangent formed at point C.
