The Geometry of Circles
This chapter zooms in on the properties of Circles and their tangents. A tangent is a line that touches the circle at exactly one point. The chapter focuses on two main theorems: firstly, that the tangent at any point of a circle is perpendicular to the radius through the point of contact; and secondly, that the lengths of tangents drawn from an external point to a circle are equal.
These simple yet powerful theorems form the basis for various geometrical proofs and calculation-based problems. The chapter helps students understand circular geometry, which is essential for fields like mechanical engineering and astronomy. The exercises encourage students to look for symmetry and congruence to solve problems efficiently.
