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.
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.
5 triangles.
A regular decagon can be divided into triangles by drawing diagonals from one vertex to all other non-adjacent vertices. This method results in a total of 8 triangles. Alternatively, using the formula for the number of triangles formed in a polygon, which is ( n - 2 ) (where ( n ) is the number of sides), a decagon (10 sides) can be divided into ( 10 - 2 = 8 ) triangles.
As many as she wants.
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
18 triangles
It can form 7 triangles
depends on what shape that vertex is in
Three 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.
