Sum of exterior angles of Concave Polygons - example

❖ In this video, we go through an example that shows the sum of the exterior angles of a concave polygon is always 360°, no matter how many sides it has. Using simple visuals and step-by-step reasoning, we explore why this property still holds true for a concave hexagon polygon, even when one of the exterior angles is negative due to a reflex interior angle. Note: A reflex angle is any angle greater than 180°. 🎯 Concepts Covered in this video: ✔ What is a concave polygon? ✔ What is an exterior angle? ✔ How exterior angles are formed in concave polygons ✔ Why the sum of the exterior angles of a concave polygon is always 360° ✔ Why one of the exterior angles is negative and how the total still adds up to 360° ✔ Note: This rule holds for any polygon, not just concave ones 🎯 We explore in this video: 🔹 How to turn at each vertex of a concave polygon 🔹 Why the total turn still equals a full circle 🔹 A visual explanation showing that the sum of exterior angles is always 360°, even with a negative angle 0:00 ❖ Introduction 0:39 – Concave Polygon Test 1:48 – Concave polygon definition 2:08 – Computing the sum of the exterior angles 11:37 – Visual Illustration 13:06 – Conclusion ✅ This video is perfect for students who want a clear and visual example of this key geometry concept. Whether you're studying for a test or reviewing fundamentals, this example will help you understand and remember why the sum of exterior angles is always 360° even for concave shapes. 🎥 Watch more triangle geometry videos in the Geometry - Triangles, Polygons & Circles Playlist.
