The sum of the internal angles of a n-sided polygon is (n-2) x 180o. For a 17-sided polygon, n = 17 and the sum of the angles is (17-2) x 180o = 2700o
There is no such polygon because a polygon must have at least 3 sides or more.
The sum of the angles of a regular n-sided polygon is equal to (n - 2) x 180 degrees.Therefore, the sum of the angles of a regular 40-sided polygon (tetradecagon) is equal to (40 - 2) x 180 = 6840 degrees. Therefore, 6840 refers to the sum of the degrees, not the number of diagonals.The number of diagonals of an n-sided polygon is given by n(n-3)/2. So a 40-sided polygon has 40*37/2=740 diagonals.

There is no such thing as a 2-sided polygon.
There is no such thing as a two-sided polygon.
Normally the minimum number sides a polygon can have is 3 which is a triangle and probably there is no such name given to a 2 sided polygon.
A 4-sided polygon has 2 diagonals. A 5-sided polygon, 5. 6-sided, 9. By induction, an n-sided polygon has 'n*(n-3)/2' diagonals. "n" is how many sides a shape has. so, (7)*(7-3)/2 now we have, 7*4/2 so, 28/2 = 14 Therefore, a 7-sided polygon would have 14 diagonals.
There aren't two sided polygons
For an n-sided polygon, the number of diagonals is 1+2+3+....+(n-4)+2(n-3). For a nine-sided polygon, there are 1+2+3+4+5+2(6)=27 diagonals.

A 3 sided polygon with 2 equal sides is an isosceles triangle
18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
