(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.
