Angles and Polygons Concepts

The video tutorial explains how to calculate the sum of internal angles in polygons using the formula (n-2) x 180, where n is the number of sides. It covers examples with triangles, quadrilaterals, pentagons, and more complex polygons, demonstrating how to apply the formula and encouraging viewers to experiment with different shapes.
