Classify Polygons Worksheets

How Do You Classify Polygons? Polygons are defined as the closed figures or shapes with three or more sides. Alternatively, any closed planar figure that is formed by the finite set of lines is known as the polygon. Polygons are grouped into three categories, namely, convex, concave, and regular. A convex polygon is the one with all its interior angles less than 180 degrees. All the vertices of the polygon will point outwards and away from the interior of the shape. A concave polygon is the one that has one or more than one interior angle greater than 180 degrees. And a regular polygon is the one that is both equiangular and equilateral. A regular polygon can either be convex or a star. Polygons are classified on the number of angles or sides they have. The commonly known polygons are listed below: A triangle is a polygon with three sides. A quadrilateral is a polygon with four sides. A pentagon is a five-sided polygon. A hexagon is a polygon that features six sides. A septagon is a polygon with seven sides. An octagon is an eight-sided polygon. A nonagon is a nine-sided polygon. A decagon is a polygon that features ten sides
