Quadrilateral: two (you can only trace one diagonal and it forms two triangles)
Hexagon: four (you can trace thre diagonals and four triangles are formed)
Octagon: six (you can trace five diagonals and six triangles are formed)
Degagon: eight (you can trace seven diagonals and eight triangles are formed)
It is always true that the number of triangles you can form from a vertex in a convex polygon is the number of sides minus 2.
