❖ Learn all about polygons in this beginner-friendly geometry video!
We explain what polygons are, how to identify them, and explore their types, properties, and angles using simple examples.

🎯 Key concepts covered:
– What makes a shape a polygon
– Types of polygons: triangle, quadrilateral, pentagon, hexagon, etc.
– Common Quadrilaterals: Square, Rectangle, Rhombus, Parallelogram, Trapezoid
– Complex (self-intersecting) polygons
– Regular vs. irregular polygons
– Interior & exterior angles
– Sum of interior angles = (n – 2) × 180°
– How to find missing angles in a polygon

✔️ What this video includes:
– Step-by-step examples to make every concept clear
– Visual explanation of regular and complex polygons
– Quick formula guide for both interior and exterior angles

🔍 Understand why shapes like cubes or circles are not polygons

🔍 See how complex polygons (self-intersecting polygons) are different from simple polygons
