4,140 degrees
The interior angles of a polygon with n sides add to (n-2)*180 degrees So, if n= 16, the sum of the interior angles is 14*180 = 2520 degrees.
7200 degrees
The 7 interior angles of a heptagon add up to 900 degrees
The 5 angles add up to 540 degrees and each interior angle measures 108 degrees
A regular polygon has all the side the same length and the same measures of angels. * * * * * Or measures of angles, even! A concave polygon has at least one angle that is reflex (between 180 and 360 degrees).
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
The three interior angles of every triangle always add up to 180 degrees. If all of them are the same measure, then each one must be 180/3 = 60 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 540 degrees
It will have 360/45 = 8 sides
The sum of the interior angles of a 13 sided polygon add up to 1980 degrees because (13-2)*180 = 1980 degrees
An octagon is a polygon that has 8 sides and 8 interior angles
