The octagon has 3 vertex diagonals such as ag ac 4 vertex diagonals such as ad af and 5 vertex diagonals such as ae.

How many diagonals does a octagon have. Thus for each of the 8 vertices you can draw 5 diagonals and hence you have constructed 5 8 40 diagonals. In the case of a concave polygon you may have to draw some of the diagonals outside the actual polygon. Draw some other polygons and count the number of diagonals.

Thus there are 20 diagonals in a regular octagon. The polygon does not have to be symmetric for this method to work. An octagon has 8 8 3 2 8 5 2 20 diagonals.

An octagon has four 4 diagonals each connecting two opposite vertices. A octagon has 20 diagonals. How many bisecting diagonals does an octagon have.

A shape s diagonals are determined by counting its number of sides subtracting three and multiplying that number by the original number of sides. Related questions how many diagonals can be. Draw an octagon select one vertex and construct each diagonal from this vertex you will see there are 5 such diagonals.

This number is then divided by two to equal the number of diagonals. An octagon has 20 diagonals. 20 diagonals for any n sided polygon the formula for the number of diagonals is n 2 x n 3 so for an octagon it is 8 2 x 8 3 4 x 5 20.

None if it is an irregular octagon. But you have constructed each diagonal twice once from each of its ends. I guess the way i would say it.
