What does a 15 sided polygon add up to?
2340 degrees
Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees.
Which polygon has 16 sides?
Hexadecagon
| Regular hexadecagon | |
|---|---|
| Type | Regular polygon |
| Edges and vertices | 16 |
| Schläfli symbol | {16}, t{8}, tt{4} |
| Coxeter–Dynkin diagrams |
What is a 17 sided polygon called?
heptadecagon
This document presents Gauss’s insight that it is possible to construct a heptadecagon— a regular polygon with 17 sides—with straightedge and compass.
How do you find the interior angles of a 15 sided polygon?
Explanation:
- the sum of the interior angles of a polygon is.
- where n is the number of sides of the polygon.
- here n=15.
- sum =180∘×13=2340∘
- one interior angle =2340∘15=156∘
How many sides does the polygon have?
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….Definition of a Polygon.
| Shape | # of Sides |
|---|---|
| Quadrilateral | 4 |
| Pentagon | 5 |
| Hexagon | 6 |
| Heptagon | 7 |

What is a polygon with 12 sides?
dodecagon
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
How many sides Pentagon have?

| 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) |
What’s a 12 sided polygon?
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
How much is each angle of a 15 sides regular polygon How much is each outer angle?
Exterior angle=24 for polygon of 15 sides.
What are the sides of a polygon?
The sides of a regular polygon are the line segments that make it up. Try this Adjust the regular polygon below by dragging any orange dot, or alter the number of sides. The length of the sides will change.
What is polygon with 16 sides called?
In mathematics, a hexadecagon (sometimes called a hexakaidecagon or 16-gon) is a sixteen-sided polygon.
What is the name of the polygon that has 15 sides?
In geometry, a pentadecagon or pentakaidecagon or 15-gon is a fifteen-sided polygon. Good A regular pentadecagon is represented by Schläfli symbol {15}. A regular pentadecagon has interior angles of 156 °, and with a side length a, has an area given by A regular triangle, decagon, and pentadecagon can not completely fill a plane vertex.
What is the interior angle of a 15 sided polygon?
Therefore all the interior angles of your 15 sided regular polygon add up to 15-2 = 13180 degrees = 2340 degrees. Therefore the internal angles are 2340/15 = 156 degrees. The sum of interior angles of a regular polygon is 3060º.
What is the angle sum for a 15 sided polygon?
What is the sum of the interior angles of a 15 sided polygon? Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees. Since the 15-gon is regular, this total is shared equally among the 15 interior angles.
