Chapter 6: Angles and Tangents of Circles
What you need to learn in this chapter
In this chapter, we will be learning about angles and tangents of circles. We will start by understanding the angle at the circumference and the central angle subtended by an arc. Next, we will explore the concept of cyclic quadrilaterals, which are quadrilaterals that can be inscribed in a circle. We will also study tangents to circles, which are lines that touch the circle at only one point. Finally, we will make and verify conjectures about the relationships between angles at the circumference and central angle subtended by particular arcs. We will use these relationships to determine the values of angles in circles and solve problems involving angles in circles.
