Can polygon have holes?

Can polygon have holes?

In geometry, a polygon with holes is an area-connected planar polygon with one external boundary and one or more interior boundaries (holes). An ordinary polygon can be called simply-connected, while a polygon-with-holes is multiply-connected.

What is the difference between a polygon and a non polygon?

A regular polygon is a polygon where all of the side lengths are equal and all of the angle measures are equal. However, the sides are not congruent. Therefore, it is an irregular pentagon. Irregular polygons have side lengths that are not congruent.

What is a polygon shape?

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”. This is because a polygon has many different angles and corners within its shape.

How many corner does a polygon have?

For example, a triangle has three sides, and a quadrilateral has four sides. So, any shape that can be drawn by connecting three straight lines is called a triangle, and any shape that can be drawn by connecting four straight lines is called a quadrilateral….Definition of a Polygon.

What it is not a polygon?

A polygon is a closed plane figure with three or more sides that are all straight. A circle is not a polygon as it does not have straight sides.

Are all closed shapes polygons?

Polygons. A polygon is any closed, 2-dimensional figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.

What do you call a 3 sided polygon?

A three-sided polygon is a triangle. There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Isosceles – has two equal sides, with the third one a different length. Two of the internal angles are equal.
