all angles are 40 degrees, therefore acute
A regular nonagon has 9 obtuse angles of 140 degrees
1 acute angle = 1 acute angle
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.
That is an acute angle. An obtuse angle is not acute.
Each angle for a regular nonagon is 140 degrees each.
An acute angle
140 degrees
acute angle
An acute angle is an angle less than 90°. So an angle of 17° is an acute angle.
An acute angle has one angle.
This is an acute angle.
A nonagon can contain angles that are acute, right, obtuse or reflex - but not straight (180 degrees).
