The image shows an angle whose rays are tangent to a circle.
A line is said to be tangent to a circle if it intersects the circle at exactly 1 point. Suppose line
Every other point on the tangent line is outside the circle, so they must all be further away from the center than the point where the tangent line intersects the circle. This means the point
A line is tangent to a circle if the line intersects the circle at exactly one point and is perpendicular to the radius.
