Question

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

Answer 1

Answer:

A. $\overline{OC} \perp \overline{AB}$

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 $\overline{AB}$ is a tangent of the circle O, at a point C, and $\overline{OC}$ is a radius, therefore, it follows that:

$\overline{OC} \perp \overline{AB}$.

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