What is the shape of polygon?
A polygon is a flat two-dimensional shape with straight sides that are fully closed. The sides must be straight, not curved. However, polygons can have any number of sides. The word polygon comes from the Greek “polugonos”.
What is the difference between a regular and irregular pentagon?
Regular shapes have sides that are all equal and interior (inside) angles that are all equal. Irregular shapes have sides and angles of any length and size.

What does a polygon shape look like?
A polygon is any shape made up of straight lines that can be drawn on a flat surface, like a piece of paper. Such shapes include squares, rectangles, triangles and pentagons but not circles or any other shape that includes a curve.
What does a polygon have to have?
Regular polygons with equal sides and angles. Polygons are two dimensional geometric objects composed of points and line segments connected together to close and form a single shape and regular polygon have all equal angles and all equal side lengths.
Which figure is a polygon?
