Definition

The point of tangency is the point where a tangent line touches the circle.

Description

The point of tangency is a critical concept in geometry, representing the single point where a tangent line meets the circle. This point is used in various applications, such as in navigation and design, where precise measurements of angles and distances are essential. In mathematics, the point of tangency is explored in the context of circle theorems, providing insights into the properties of tangents and circles. In education, understanding the point of tangency helps students develop geometric reasoning and problem-solving skills, which are essential for advanced studies in geometry and trigonometry.
