    It doesn't even look like AB is a tangent in your picture.

    Ok. We know that a radius is perpendicular to a tangent at the point of tangency. Sp we want to know if the radius CB is perpendicular to the proposed tangent AB. We can use the Pythagorean Theorem to find out if ABC is a right triangle. Is it?

    So then, CB is perpendicular to AB and CB is a radius so AB must be a tangent.
