A hexagon has 9 diagonals. Each vertex of a n-sided polygon can be connected to n - 3 others with diagonals. Thus n(n - 3) possible diagonals. However, when Vertex A is connected to vertex C, vertex C is also connected to vertex A, thus each diagonal is counted twice. Thus: number_of_diagonals = n(n - 3)/2 = 6(6-3)/2 = 6x3/2 = 9
Trace diagonals that connect opposite vertex through the center
There can be 14 lines in a seven side shape * * * * * That is the total number of diagonals from ALL vertices. Not what the question asked, though. From one vertex, there can be 4. One to every other vertex except for itself and one each on either side.
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
Two triangles can be formed by the diagonals of one vertex of a four-sided polygon.
4 are formed
5 triangles are formed.
depends on what shape that vertex is in
1 triangle is formed.
