What you need to learn in this chapter
In this chapter, we will be learning about polygons. We will start by understanding regular polygons, which are polygons with equal sides and equal angles. We will learn about their geometric properties and how to represent them in different ways. Next, we will explore the interior angles and exterior angles of polygons. We will learn how to calculate these angles and understand their relationships. We will also learn how to construct regular polygons using different methods and explain why each step is important. Let's dive into the world of polygons and discover their fascinating properties!
