Скачать или смотреть Sum of exterior angles of a Triangle - proof

❖ In this video, we prove that the sum of the exterior angles of a triangle is 360 degrees. Using clear explanations and simple geometry concepts, you'll learn how this fundamental property is derived visually and intuitively.

🎯 Concepts Covered in this video:
✔ What is an exterior angle
✔ Turning around a triangle
✔ Connecting the exterior angles of a triangle to the 360° of a full circle

🎯 We explore in this video:
• How extending the sides of a triangle creates exterior angles
• Why turning at each vertex always leads to a full 360° rotation
• A step-by-step visual proof by cutting and pasting the exterior angles and removing the interior angles to show that the sum of the exterior angles of a triangle is 360 degrees.
