A polygon is also known as a multilateral. This term comes from the prefix ‘multi-‘, meaning ‘many’, and ‘lateral’, referring to ‘sides’. Therefore, a multilateral is a shape formed by multiple straight lines connected to form a closed figure.
Polygons can be regular, where all sides and angles are equal, or irregular, where they are not. Common examples of polygons include triangles, quadrilaterals, pentagons, and hexagons. Understanding polygons is essential in geometry, as they are the building blocks for more complex shapes and structures.
