What is the Tangent Line to Circle Theorem?

The Tangent Line to Circle Theorem states that a line is tangent to a circle if and only if it's perpendicular to the circle's radius.


what are endpoints on the diameter?

What is the Radius tangent theorem?

The tangent of a circle always meets the radius of a circle at right angles.


What does the radius-tangent theorem state?

The radius-tangent theorem states that a radius drawn to the point of tangency of a circle is perpendicular to the tangent line at that point. This theorem is based on the fact that the radius of a circle is always perpendicular to the tangent line at the point where the tangent touches the circle. This relationship is crucial in geometry and helps in solving various problems related to circles and tangents.
