The best I can figure, I can make 13

To create a hexagon using triangles, you can divide the hexagon into 6 equilateral triangles by drawing lines from each vertex to the center of the hexagon. Therefore, it would take 6 triangles to completely fill a hexagon.
6 straight lines drawn inside of an octagon will divide the octagon into 8 triangles

Draw a line from the midpoint of each side of the triangle to opposite corner. All three lines should intersect at the center of the original triangle and six smaller triangles will be formed. There are likely other solutions, but this is the easiest one.

4 triangles make 1 hexagon. (easy way to find out how many triangles there are in a polygon- take number of sides of the polygon, subtract 2 from it, that's your answer!)

6 Triangles!!
Join the 6 triangles like pizza slices
