An octagon can be divided into triangles by drawing diagonals from one vertex to all non-adjacent vertices. Specifically, an octagon has 8 sides, and the number of triangles that can be formed from its vertices is calculated using the formula for combinations: ( \binom{n}{3} ), where ( n ) is the number of vertices. For an octagon, this gives ( \binom{8}{3} = 56 ) triangles. Therefore, there are 56 unique triangles that can be formed using the vertices of an octagon.
