Question

Answer 1

hexagon.
n(n-3/2)= 3/2n
n=6(sides of a hexagon)

Answer 2

hexagon.
n(n-3/2)= 3/2n
n=6(sides of a hexagon)

Answer 3

hexagon

Answer 4

hexagon

Answer 5

Number of diagonals is n(n-3)/2

n(n-3)/2 = 3n/2
n(n-3) = 3n
n = 6 (hexagon)

Answer 6

Number of diagonals is n(n-3)/2

n(n-3)/2 = 3n/2
n(n-3) = 3n
n = 6 (hexagon)
