What is the Type of Tangents to Circles?
A tangent touches a circle at exactly one point and is always perpendicular to the radius drawn to that point. Two tangents from the same external point are equal in length. Perpendicular to Radius: The radius drawn to the point of tangency is always perpendicular to the tangent. In other words, the angle between the […]
