❖ In this lesson, we prove that the sum of the exterior angles of any convex polygon is always \(360^\circ\), no matter how many sides it has.

Using simple visuals and step-by-step reasoning, we explore why this geometric property works for triangles, quadrilaterals, pentagons, hexagon, and beyond.

🎯 Concepts Covered in this lesson:

✔ What is a convex polygon?

✔ What is an exterior angle?

✔ How exterior angles are formed in convex polygons

✔ Why the sum of the exterior angles of a convex polygon is always \(360^\circ\)

✔ Note: This property also holds for any polygon, not just convex ones

🎯 We explore in this lesson:

🔹 How to turn at each vertex of a convex polygon

🔹 Why the total turn still equals a full circle

🔹 A visual proof showing why the exterior angles of a convex polygon always sum to \(360^\circ\)

✅ This lesson is perfect for students and learners who want a straightforward explanation of this fundamental geometry concept. Whether you are studying for a test or just brushing up on your geometry skills, this lesson makes the proof easy to understand!
