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.
How many diagonals can be drawn from one vertex of a decagon?
Oh, dude, a decagon has 10 sides, right? So, if you pick one vertex and want to draw diagonals, you can draw diagonals to all the other vertices except the adjacent ones, which are already sides. So, you can draw 7 diagonals from that one vertex. Math can be fun, like a puzzle... or a headache, depending on how you look at it.
