Do polygons have 4 sides

Answer 1

Polygon is a general term describing a closed figure with 3 or more sides. A triangle, then, is a 3-sided polygon, a square or trapezoid is a 4-sided polygon. You could have a polygon that has 18 sides, but the more sides the figure has, the more it approaches being a circle, and the harder it is to even tell that it's a polygon.
