The segments are called the sides of the polygons, and the points where the segments intersect are called vertices. The easiest way to identify a polygon is to look for a closed figure with no curved sides. Polygons can be either convex or concave. Think of the term concave as referring to a cave, or “caving in”.
Are the sides of a polygon?
The segments of a polygonal circuit are called its edges or sides. The points where two edges meet are the polygon’s vertices (singular: vertex) or corners. The interior of a solid polygon is sometimes called its body. An n-gon is a polygon with n sides; for example, a triangle is a 3-gon.
How many sides square have?

What is polygon and types of polygon?
A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.
How many sides Pentagon have?
five sides
| Pentagon | |
|---|---|
| An equilateral pentagon, i.e. a pentagon whose five sides all have the same length | |
| Edges and vertices | 5 |
| Internal angle (degrees) | 108° (if equiangular, including regular) |
How many sides are there?
Shapes and Number of Sides
| Shape Name | Number of Sides |
|---|---|
| Triangle | 3 |
| Quadrilateral | 4 |
| Pentagon | 5 |
| Hexagon | 6 |
How many sides are pentagon?
five
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.
What is a polygon with 3 sides?
triangle

How can you identify and classify polygons?
Polygons are classified and described by the number of sides, the kind of angles, and whether any of the sides are the same length (or congruent). Many polygons have special names. This figure shows the most common polygons. Notice that we identified a 4-sided polygon as a quadrilateral.
How do you classify polygons?
You can classify polygons by the number of sides. A three sided polygon is a triangle, a four sided polygon is a quadrilateral, and so on. You can also classify them by the angles. If all the interior angles are smaller in measure than the exterior angles, the polygon is convex.
What are four types of polygons?
The different types of polygons include convex, concave, regular, irregular, simple or complex. Polygons will have half of these qualities.
Which classification correctly describes the polygon?
Classification of Polygons. A polygon may be identified by the number of sides. (1) A polygon with 4 sides is called a quadrilateral. (2) A polygon of 5 sides is called a pentagon. A polygon of 8 sides is called an octagon. A polygon of 10 sides is called a decagon. A polygon of 12 sides is called a dodecagon.
