What is a regular polygon? State the name of a regular polygon of (i) 3 sides  (ii)  4 sides (iii)  6 sides

Find the measure of each exterior angle of a regular polygon of(i) 9 sides (ii) 15 sides

Calculate the sum of angles of a polygon with : (i) 10 sides (ii) 12 sides (iii) 20 sides

Express in radians and also in degrees the angle of a regular polygon of (1) 40 sides, (ii) n sides.

The number of diagonals of a polygon of 15 sides is:

The number of diagonals of a polygon of 20 of sides

If the difference between an interior angle of a regular polygon of (n + 1) sides and an interior angle of a regular polygon of n sides is 4^(@) , find the value of n. Also, state the difference between their exterior angles.

If the difference between an exterior angle of a regular polygon of 'n' sides and an exterior angle of another regular polygon of '(n+1)' sides is equal to 5^(@) , find the value of 'n'.

Find the sum of exterior angles obtained on producing, in order, the sides of a polygon with: (i) 7 sides (ii) 10 sides (iii) 250 sides

Each interior angle of a regular polygon is 160^(@) . Find the interior angle of another regular polygon whose number of sides is two-thirds the number of sides of the given polygon.

Each interior angle of a regular plygon is 144^(@) . Find the interior angle of a regular polygon which has double the number of sides as the first polygon.
