Providing that it is a regular polygon then it is a nonagon which has 9 sides
If you name the degree of the angle d, then the exterior angle is 180 - d. The exterior angles have to add up to 360, a full circle to get back to where you started. So if there are nsides and n angles,n(180-d) = 360Solving for d, you get180 n - nd = 360-nd = 360 - 180n-d = 360/n - 180and thend = 180 - 360/n
There is no special name for a 120º angle.
That is a straight angle.
It is a regular 8 sided octagon whereas each interior angle is 135 degrees and each exterior angle is 45 degrees.
It is a regular 5 sided pentagon
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
It has 9 sides and is called a nonagon
It is a regular 8 sided octagon whose interior angles are 135 degrees and its exterior angles are 45 degrees
an octagon (8-sided)
Right angle not polygon. (i'm not mad).
It is a regular octagon which has 8 sides
an Octagon, because 360/8=45.
Assuming the question refers to all interior angles of 60 degrees, then the answer is an equilateral triangle. If it is just one angle being 60 degrees, it can be any polygon you like.
It is a triacontagon, or 30-sided shape.The formula for one interior angle of a regular n-sided polygon is 180(n-2)/nwhere 180 (28) / 30 = 168*You can QUICKLY and EASILY find the answer using the formula for one exterior angle : it is 360/n360/30 = 12 and the interior angle is 180-12 = 168.The algebraic equation is(180-168) n = 360
It is called megagon, its internal angle's sum is 179999640 degrees (that a lot!)
