Introduction to Polygons

A polygon is a closed figure made of line segments that intersect only at endpoints. It has at least 3 sides. Polygons are classified by the number of sides, such as triangles (3 sides), quadrilaterals (4 sides), and pentagons (5 sides). Polygons can also be classified as convex or nonconvex, where a convex polygon's diagonals are inside the figure and a nonconvex polygon has at least one diagonal outside the figure.
Introduction to Polygons
- 3. POLYGON ● It is a closed figure made up of line segments that intersect only at their endpoints. ● It comes from the Greek word poly which means “many” and gonia which means “angle”. ● It can have at least 3 sides. The sides of a polygon do not cross each other between their endpoints. Each endpoint where two sides meet is called vertex. 01 02 03 04 05 Index
