Introduction to Tangents and Angles of a Circle

Tangents have several important applications across various fields, particularly in mathematics, physics, engineering, and geometry. Some applications of tangents are:

Tangents play an important role in the study of curves. They are lines that touch a curve at a single point, perpendicular to the curve's radius at that point. Tangents are used to define geometric properties such as the radius, diameter, chord, and arc length of circles.
