They can be but don't have to. An irregular one doesn't, but a regular one does.
It is a nonagon in which all the sides have the same length. This should not be confused with a regular nonagon which also requires all angles to be the same.
what is the total of interior angles in a nonagon?
A nonagon has 9 sides and 9 angles.
what is the total of interior angles of the nonagon
A convex nonagon can have between zero (0) and three (3) right angles. A general nonagon can have between zero (0) and six (6) right angles.
A nonagon has nine interior angles. The sum of the interior angles of a nonagon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a nonagon, this is ( (9 - 2) \times 180^\circ = 1260^\circ ). While it's possible to have acute angles in a nonagon, the specific number of acute angles can vary based on the shape; however, it can contain a maximum of 7 acute angles, depending on the arrangement of the angles.
The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.
A nonagon can contain angles that are acute, right, obtuse or reflex - but not straight (180 degrees).
The sum of the interior angles of a nonagon is 1260 degrees.
In a regular nonagon there are 9, if its irregular its dependant.
None.
Sum of interior angles of a nonagon = (n-2)*180 = 7*180 = 1260 degrees. That is as far as you can go with the information given. If, and there is no reason to assume so, the nonagon is regular then the internal angles are the same and each is 1260*9 = 140 degrees.
