External angles would total 360 degrees; internal angles would total 14,400 degrees.
The measure of a single internal angle of any regular polygon is equal to 180 (n - 2) / n. Therefore, an internal angle of a regular icosikaiheptagon (27-sided polygon) is equal to 13.3 recurring, or 13 and one third, degrees. It thereby follows that a measure of the external angle of the same polygon is equal to 180 - 13 and one third = 166.6 recurring, or 166 and two thirds, degrees.
If the interior angle is 120° then the external angle is 180 - 120 = 60° Number of sides = 360 ÷ 60 = 6. The polygon is a Hexagon.
The exterior angles of any polygon add up to 360° (imagine walking round any polygon - you will have made a complete turn). There are six external angles in a hexagon. If it is a regular hexagon, each external angle will be 360°/6 = 60°.
The octagon. The rule is that as the number of sides of a regular polygon increases then the external angle decreases while the interior angle increases The summation of the interior and external angleof one vertex is 180o.
The interior angle of a polygon is the angle formed by two adjacent sides of a polygon where the angle lies inside the area formed by the polygon. The exterior angle is that formed by one of these sides and the line formed by extending the other side. Consequently, External angle = 180 deg - Internal angle. Because they form supplementary angles, it does not matter which of the two sides you extend.
They are supplementary angles. That is, their sum is 180 degrees (or pi radians).
A square is a polygon, not an 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
Internal angle = 150° → external angle = 360° - 150° = 30° number of sides = 360 ° ÷ external angle = 360° ÷ 30° = 12 It has 12 sides.
No, they are supplementary, not complementary.
The external angle of a polygon is equal to 360/n, n representing the number of sides in the polygon. Since an octagon has eight sides, the external angle of a regular octagon is 360/8 = 45 degrees. Since a straight angle in a polygon would be equal to 180 degrees, you subtract the measure of the external angle from this, to make an internal angle of 180 - 45 = 135 degrees.
The sum of all the internal angles of a polygon with n sides is 180*(n-2) degrees. In a regula polygon, therefore, each internal angle is 180*(n-2)/n degrees. Also The sum of all the external angles in 360 degrees. The sum of each external angle in a regular polygon is 360/n degrees.
A polygon (with more than 3 sides) can have an angle of any measure between 0 and 360 degrees. If it is a reflex angle, it cannot have a supplement. Even if a supplementary angle exists, its size is indeterminate.
Each vertex angle of a polygon is composed of an external angle and an interior angle. These two angles are supplementary (total 180°). As the number of sides of a regular polygon increases then the external angle decreases and conversely, the interior angle increases. The interior angle of a regular pentagon (108°) is larger than the interior angle of a square (90°).
A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.A regular polygon cannot have an internal angle of 10 degrees and any irregular polygon can.
Sum of external angles of a polygon = 360 degrees. So for a regular 16-gon, each EXTERNAL angles = 360/16 = 22.5 degrees. So each internal angle = 180 - external angle = 180 - 22.5 = 157.5 degrees.
