Correct Answer - Option 2 : 14
Given:
Regular heptagon has 7 sides
Formula Used:
Number of diagonals = n (n - 3)/2
Calculation:
Number of diagonals = n (n - 3)/2
n = 7
⇒ Number of diagonals = 7 (7 - 3)/2
⇒ Number of diagonals = (7 × 4)/2
⇒ Number of diagonals = 14
∴ A regular heptagon has 14 diagonals.
The correct option is 2 i.e. 14
