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.

How many diagonals does a 8 sided polygon have?
An eight-sided polygon has 8 vertices. Consider1st vertex = 7 diagonals to other vertices2nd vertex = 6 diagonals to other vertices (since one has now been used)3rd vertex = 54th vertex = 45th vertex = 36th vertex = 27th vertex = 18th vertex = 0, so7+6+5+4+3+2+1 = 28Improved Answer:-Formula for finding diagonals of a polygon 0.5*(n2-3n) when n is the number of sides0.5*(82-24) = 20 diagonals
How many triangles can a 7 sided polygon have?

What is a 27 sided shpe called?
A 27-sided shape is called a heptacosagon. The prefix "hepta-" denotes the number 7, and the suffix "-gon" signifies a polygon with that many sides. Therefore, a 27-sided polygon is specifically referred to as a heptacosagon in geometry.
Which is the regular polygon are the diagonals double the number of sides?
The number of diagonals in a polygon with n sides is n*(n-3)/2 This is double the number of sides so n*(n-3)/2 = 2*n That is n*(n-3) = 4n Dividing both sides by n gives (n-3) = 4 So that n = 7. A heptagon has 7*4/2 = 14 diagonals.
