All you can say about it is that it's "equiangular" ... a big word that means all of
its angles measure the same size.
At first, one might think that a polygon with all angles equal is "regular" ... that if
all of its angles are equal, then its sides must also be all of the same length. But
that's only true of a triangle, and doesn't hold for polygons with more than three
sides. Example: A rectangle has all angles equal, but not its sides.
An angle with measure equal to 90 is called a right angle.
The equation for finding the interior angle measures of a regular n-gon is (n-2)*180/n. Thus, if this is set equal to 176 and solved for n, n is found to be 90. Therefore, a regular polygon with each interior angle measure equal to 176, has 90 sides.
A regular polygon is a polygon in which all sides are of the same length and all angle are of the same measure. A trapezoid (trapezium to most people) is a four sided polygon or a quadrilateral. If its sides and angles were all equal, the quadrilateral would have to be a square.
The angle sum of a polygon is always 360 degrees. If all angles are equal, then each angle is 18 degrees. Simply divide 360 by 20.
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress ?
a "regular" polygon
A regular polygon has sides of equal length and each interior angle is the same measure
An angle with measure equal to 90 is called a right angle.
A regular hexagon which has 6 equal sides and 6 equal angles.
Each interior angle of a regular polygon has a measure that is equal to one hundred and eighty degrees times two less than the number of sides in the polygon.
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.
It will have 10 equal sides
All of the angles are equal in a "regular" polygon. (All of the sides are too.)
The polygon will have 12 equal sides and each interior angle measures 150 degrees.
18 sides
It is then called a regular polygon when all angles and sides are of equal values.
