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 hexagon can be divided into four triangles by drawing all of the diagonals from one vertex. Since a hexagon has six sides, drawing diagonals from one vertex creates three additional triangles, resulting in a total of four triangles (the original triangle formed by the vertex and two adjacent vertices, plus the three formed by the diagonals).
5 triangles.

Number of sides minus 2 equals the number of triangles within the polygon.

A hexagon can be divided into four triangles by drawing all of the diagonals from one vertex. Since a hexagon has six sides, drawing diagonals from one vertex creates three additional triangles, resulting in a total of four triangles (the original triangle formed by the vertex and two adjacent vertices, plus the three formed by the diagonals).
5 triangles.
depends on what shape that vertex is in
A heptagon has seven sides, so when drawing diagonals from one vertex, it will create five triangles. This is because each diagonal drawn from a single vertex will create a triangle until it intersects the previous diagonal. Therefore, the number of triangles formed by drawing all diagonals from one vertex in a heptagon is five.
You Can Get 6 triangles

A hexagon (six-sided polygon) can be divided into 4 triangles by drawing all of the diagonals from one vertex (only three lines can be drawn in this case, since each vertex already connects to two others on the edges of the form). If you instead drew lines from the center to each vertex, you would get 6 triangles.
Number of sides minus 2 equals the number of triangles within the polygon.
