How many acute angles in an nonagon?

Answer 1

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.
