Angles In Polygons - GCSE Maths - Steps, Examples & Worksheet


In the world of geometry, polygons are a fundamental concept. They appear everywhere, from the angles in a basketball court to the design of your smartphone. To fully grasp the intricacies of polygons, you need to be well-versed in a variety of skills. In this article, we will explore six essential skills to help you master the angles of polygons.

1. Understanding the Basics: What is a Polygon?

Before delving into angles, it’s crucial to understand what a polygon is. A polygon is a two-dimensional closed shape with straight sides. This section will introduce the concept and various types of polygons, setting the stage for a deeper exploration of their angles.

2. Sum of Interior Angles

One of the fundamental principles in polygon geometry is the sum of interior angles. In this section, we will discuss how to calculate this sum for different types of polygons, such as triangles, quadrilaterals, and more complex shapes. Knowing this skill is vital for solving a wide range of geometric problems.

3. Exterior Angles

Understanding exterior angles is another key aspect of mastering polygons. This section will teach you how to calculate exterior angles, their properties, and how they relate to interior angles. Practical examples will help illustrate their importance.

4. Properties of Regular Polygons

Regular polygons have equal sides and equal angles. Knowing the properties of regular polygons will enable you to work with symmetry and precision. This section will explore the characteristics of regular polygons and how to calculate their angles efficiently.

5. Using Trigonometry in Polygon Angles

Trigonometry plays a crucial role in calculating angles within polygons, especially in more complex scenarios. This section will introduce you to trigonometric concepts and how to apply them to solve polygon angle problems.

6. Practical Applications

This section will take a real-world approach to the topic. We will discuss how understanding polygon angles can be applied in various fields, from architecture and engineering to graphic design and even video game development. Real-life examples will highlight the significance of these skills.


Mastering the angles of polygons is not only a fascinating journey into geometry but also an essential skill in many professional fields. By understanding the basics, calculating interior and exterior angles, grasping regular polygon properties, using trigonometry, and applying these skills in real-world contexts, you can become a geometry virtuoso.

Get ready to explore the world of polygons, calculate their angles, and apply your newfound knowledge in exciting ways. With these essential skills, you’ll be well-equipped to tackle any polygon-related challenge that comes your way.
