In two dimensions 6 triangles meet at a vertex. In 3-dimensions any number of triangles (greater than 2) can meet at a vertext - a pyramid with the base in the shape of an n-gon will have n triangles meeting at its apex.
A polygon with ( n ) sides can be divided into ( n - 2 ) triangles by drawing all the diagonals from one vertex. This is because each diagonal connects the chosen vertex to another vertex, forming a triangle with each adjacent pair of vertices. Therefore, for a polygon with ( n ) sides, you will create ( n - 2 ) triangles in total.
A tridecagon has 13 sides and can be divided into triangles by drawing diagonals from one vertex to all other non-adjacent vertices. This results in exactly 11 triangles, as each vertex connects to 10 other vertices, but each triangle shares sides with others. Therefore, the number of triangles that can be formed within a tridecagon is 11.
A regular hexagon can be divided into 6 rhombuses by connecting each vertex to the center and drawing lines between adjacent vertices. Each pair of adjacent triangles formed by these lines can be rearranged to form a rhombus. Therefore, there are 6 rhombuses within a regular hexagon.
That shape is a unit equilateral triangular dipyramid, and it has 6 faces.
Two triangles can be formed by the diagonals of one vertex of a four-sided polygon.

If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
It can form 7 triangles
18 triangles

3 triangles
5 triangles are formed.
You Can Get 6 triangles
The number of triangles that can be formed within a regular polygon depends on the number of sides the polygon has. For an n-sided polygon, where n is greater than or equal to 3, you can form n-2 triangles within the polygon. This is because each triangle is formed by connecting one vertex to any other two non-adjacent vertices. So, for example, in a regular pentagon (5-sided polygon), you can form 5-2 = 3 triangles.
