❖ Learn all about polygons in this beginner-friendly geometry lesson! 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 \(= (n – 2) × 180^\circ\)

– How to find missing angles in a polygon

✔️ What this lesson 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

🎯 Whether you’re a student, teacher, or just love math, this lesson will help you master the basics of polygons!
