These shapes are known as regular polygons. A polygon is a many sided shape with straight sides.
To be a regular polygon all the sides and angles must be the same.
The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
-27
23 of them because total angles are (25-2)*180 = 4140 degrees
The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees So (n-2)*180 = 4500 Hence n - 2 = 4500/180 = 25 and then n = 25 + 2 = 27.
Well, honey, a 25 sided polygon is called a "icosikaihenagon." Yes, it's a mouthful, just like your nosy neighbor's gossip. So next time you need to impress someone with your geometry knowledge, just drop that bombshell of a word and watch them squirm.
It is quite acceptable to call them 13-25-agons but what's more important is knowing how to work out their properties.
A 25 sided polygon is called a icosikaipentagon.
Mathematicians call it a 25 sided polygon or a 25-gon. ICOSITEPENTAGON
It has 25 sides.
A 25-sided polygon is an icosikaipentagon, an icosipentagon, or icosapentagon.It is also acceptable to call it a 25-agon.A 25 sided shape is called an icosikaipentagon.icosakiatatriagonmost people call it a 25-gon
The formula for the sum of the interior angles of a polygon is: 180 * (n - 2) where n is the number of sides of the polygon. So the sum of the angles of a polygon with 25 sides is 180 * 23 = 4,140.

There are 275 diagonals in a 25 sided polygon
It is: 360/25 = 14.4 degrees
