List of top Mathematics Questions on Polygons

The interior angles of a polygon with \( n \) sides, are in an A.P. with common difference 6°. If the largest interior angle of the polygon is 219°, then \( n \) is equal to:
If a polygon of \( n \) sides has 275 diagonals, then \( n \) is:
If the number of diagonals of a regular polygon of \( n \) sides is 104, then \( n = \)
If a polygon of \(n\) sides has \(560\) diagonals, then \(n=\)
