In this lesson, we explore the different Types of Polygons and how they are classified. A polygon is a closed shape made of straight-line segments, and they come in many forms!

👉 We cover:

✅ The meaning of “polygon” (Greek roots: poly- = “many”, -gon = “angle”)

✅ Naming polygons based on the number of sides (Triangle, Quadrilateral, Pentagon, etc.)

✅ The classification of polygons:

By Side Length & Angles:

Regular Polygon: All sides and angles are equal.

Irregular Polygon: Sides and angles are not equal.

By Angles:

Convex Polygon: All interior angles are less than \(180^\circ\).

Concave Polygon: At least one interior angle is greater than \(180^\circ\).

By Structure:

Simple Polygon: Non-intersecting sides.

Complex Polygon: Self-intersecting (crossing sides).
