Exterior angles add up to 360 degrees Interior angles add up to 4140 degrees
Method 1: Interior angles of a regular n-sided polygon total (2n - 4) right angles or 180n - 360 degrees. Each angle is therefore ((180 x 25) - 360)/25 ie 165.6 degrees. Method 2: EXterior angles of regular n-sided polygon = 360/n degrees, in this case 360/25 ie 14.4 degrees. Interior angle = 180 - exterior ie 180 - 14.4 = 165.6 degrees.
None. Since the number of sides is odd, there can be no parallel sides.
Because 25 does not divide 360.
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
4,140 degrees
It is: 360/25 = 14.4 degrees
4140
4140
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
It has 23 triangles
4,140 degrees, or 23 'straight' angles.

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.
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
