Download Solution PDFGiven:
Regular polygon with 9 sides
Formula used:
The number of diagonals in a polygon is calculated using the formula:
D = n(n - 3) / 2
Where, n = number of sides of the polygon
Calculation:
For a polygon with 9 sides, n = 9
D = n(n - 3) / 2
⇒ D = 9(6) / 2
⇒ D = 54 / 2
⇒ D = 27
∴ The number of diagonals that can be drawn in a regular polygon with 9 sides is 27.
Hence, the correct option is 1) 27.
