A 1980 sided polygon makes 1980 vertices.
The interior angles of a 13 sided polygon add up to 1980 degrees
A 13 sided polygon interior angles add up to 1980 degrees
It will have (1980+360)/180 = 13 sides
It will have (1980+360)/180 = 13 sides

Suppose the polygon has V vertices.Then sum of interior angles is (V - 2)*180 degrees = 1980 degrees => V - 2 = 1980/180 = 11 => V = 13 A polygon with V vertices has V*(V-3)/2 = 13*10/2 = 65 diagonals.

1980 degrees
A polygon's number of sides can be determined using the formula for the sum of the interior angles, which is ((n - 2) \times 180) degrees, where (n) is the number of sides. Setting this equal to 1980 degrees, we have ((n - 2) \times 180 = 1980). Solving for (n), we find (n - 2 = 11), so (n = 13). Thus, a 1980-degree polygon has 13 sides.
