AnswerA tetrakaidecagon is a 14-sided polygon.
12=)Improved Answer:-It has 14 because the formula of 0.5*(49-27) = 14 diagonals
A 7 sided polygon has 14 diagonals
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.
