Chapter 1: Circular Measure
What you need to learn in this chapter
In this chapter, we will be learning about circular measure in Additional Mathematics.
We will start by understanding radians, which is a unit of measurement for angles in a circle.
Next, we will explore how to find the arc length of a circle, which is the distance along the circumference.
We will also learn how to calculate the area of a sector of a circle, which is a portion of the circle enclosed by two radii and an arc.
Lastly, we will apply our knowledge of circular measure to solve problems involving angle measurements, arc length, radius, and the angle at the center of a circle.
