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

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.
