(i)A convex quadrilateral
For a convex quadrilateral us shall usage the formula n(n-3)/2
So, number of diagonals = 4(4-3)/2 = 4/2 = 2
A convex quadrilateral has actually 2 diagonals
(ii)A consistent hexagon
For a continual hexagon us shall use the formula n(n-3)/2
So, number of diagonals = 6(6-3)/2 = 18/2 = 9
A consistent hexagon has 9 diagonals.
You are watching: How many diagonals does a hexagon have
(iii) A triangle
For a triangle us shall usage the formula n(n-3)/2
So, number of diagonals = 3(3-3)/2 = 0/2 = 0
A triangle has no diagonals.

(i)A convex quadrilateral
For a convex quadrilateral us shall usage the formula n(n-3)/2
So, variety of diagonals = 4(4-3)/2 = 4/2 = 2
A convex quadrilateral has actually 2 diagonals
(ii)A constant hexagon
For a continuous hexagon us shall use the formula n(n-3)/2
So, variety of diagonals = 6(6-3)/2 = 18/2 = 9
A consistent hexagon has actually 9 diagonals.
(iii) A triangle
For a triangle us shall usage the formula n(n-3)/2
So, variety of diagonals = 3(3-3)/2 = 0/2 = 0
A triangle has no diagonals.
