❖ Learn how to find missing interior and exterior angles of a concave polygons using simple rules and a clear example!

In this video, we walk through a concave polygon which is an irregular polygon.

For this concave polygon, we find:
✔️ the missing interior angle x
✔️ the missing exterior angle y

🎯 Key concepts covered:
– What is a concave polygon?
– Sum of interior angles = (n – 2) × 180°
– Sum of exterior angles = 360°
– Exterior Angle = 180° – Interior Angle

You’ll see two different ways to solve the example, so you can clearly understand both approaches.

🔍 Learn how the exterior angles of any polygon always add up to 360 degree, just like a full circle. It’s a simple but powerful idea that works for every polygon!
