A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
1800 degrees (that is the sum of the internal angles of the 12-sided polygon).
A 13 sided polygon also called a triskaidecagon or tridecaogn has a total 1980 degrees for its interior angles.
(number of sides -2)*180 = sum of interior angles
30 sides
eight angles
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
Polygon is a two dimensional figure that has three or more sides. Polygons are classified by their number of sides. Three sided is a triangle. A four sided figure is a quadrilateral. A five sided figure is a pentagon and so forth. The number of angles it has is equal to the number of sides.A polygon usaally has 5sides
The interior angles of a fifteen sided polygon amount to 2340 degrees.
The interior angles of a 13 sided polygon add up to 1980 degrees
1800 degrees (that is the sum of the internal angles of the 12-sided polygon).

A 13 sided polygon also called a triskaidecagon or tridecaogn has a total 1980 degrees for its interior angles.
If a solid, it is called a "Polyhedron". If just lines in three dimensions, its called a "Three Dimensional Polygon". Polyhedron derives from Greek words for "many faced" or "many sided". Polygon derives from "many angles"
(number of sides -2)*180 = sum of interior angles
There are three diagonal lines in a six sided Polygon(Hexagon)
