Circles, IVTangentsDefinition - TangentsRay BC is tangent to circle A, because the line containing BC intersects the circle in exactly one point. This point is called the point of tangency.
TheoremIf a line is tangent to a circle, then it is perpendicular to the radius drawn to the point of tangency.
