Real-world examples of polygons with identified attributes

📚 Quick Study Guide

📐 Polygon Definition: A closed, two-dimensional shape formed by straight line segments. 🛑 Regular Polygon: A polygon with all sides and all angles equal. 🔢 Irregular Polygon: A polygon where sides and/or angles are not all equal. ➕ Convex Polygon: A polygon where all interior angles are less than 180 degrees. A line segment between any two points inside the polygon lies entirely inside the polygon. ➖ Concave Polygon: A polygon with at least one interior angle greater than 180 degrees. A line segment between two points inside the polygon may pass outside the polygon. ➗ Naming Polygons: Triangles (3 sides), Quadrilaterals (4 sides), Pentagons (5 sides), Hexagons (6 sides), Heptagons (7 sides), Octagons (8 sides), etc. 💡 Key Attributes: Sides, angles, vertices (corners).
