There are 275 diagonals in a 25 sided polygon
0.5*(25-15) = 5 diagonals
It has 23 triangles
A 25 sided polygon is called a icosikaipentagon.
Mathematicians call it a 25 sided polygon or a 25-gon. ICOSITEPENTAGON
There are 275 diagonals in a 25 sided polygon
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
(25-2)*180 = 4140 degrees
1/2*(252-75) = 275 diagonals
0.5*(25-15) = 5 diagonals
It has 23 triangles
If: 180 -165.6 = 14.4 degrees for each exterior angle Then: 360/14.4 = 25 sides So: 0.5*(25^2 -3*25) = 275 diagonals

Yes, if the shape happened to be a pentagon ( 5 sided figure ) , each side could be 5 meters and 5 times 5 is equal to 25.
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
