The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
48 sides A formula for finding the number of sides of a regular polygon given an interior angle: 360/(180-angle)=sides
If each interior angle is 178 degrees then the regular polygon will have 180 sides.
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
The polygon has 16 sides :)
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
Providing that its a regular polygon then it will have 12 sides
Well, honey, a polygon with an interior angle of 10 degrees would have 36 sides. Each interior angle of a polygon can be calculated using the formula (n-2) * 180 / n, where n is the number of sides. So, in this case, you would solve for n by setting 10 = (n-2) * 180 / n. Math can be a real hoot sometimes!
For a regular polygon the internal angle between two sides is (180 - (360/n)) degrees where n is the number of sides. A regular polygon is one where all side lengths and angles are the same.
To find the internal angle of a regular polygon with sides n, (n-2)/n * 180 3/5 * 180 = 108
With a regular polygon: 360/exterior angle = number of sides
Check out this webpage: http://en.wikipedia.org/wiki/Regular_polygon The internal angle of a regular polygon = (1-2/No. of sides) x 180 If the no. of sides of a regular polygon is P, then, 162 = (1-2/P) x 180 or P=20 sides
Each internal angle would be 180*(n-2)/n degrees where n is the number of sides in the polygon.
360/exterior angle = number of sides of a regular polygon
Exterior angle regular polygon = 360° ÷ number of sides = 360° ÷ W Interior angle regular polygon = 180° - exterior angle regular polygon = 180° - (360° ÷ number of sides ) = 180° - (360° ÷ W)
5 sides, a regular pentagon.
