Find Missing Interior Angles of a Polygon

❖ In this video, we find the missing interior angles of a polygon using clear explanations and simple methods.

We apply the formula:

🔹 Sum of Interior Angles = (n - 2) × 180°

to different regular and irregular polygons, from triangles to hexagons, to see how it works in practice.

If you ever forget the formula, just remember that you can find the sum of interior angles by splitting the polygon into triangles - a simple way to understand why the formula holds.

This video walks through various examples to help you confidently apply the formula and find missing interior angles.
