Count the number of triangles for which one of the vertices is $1$. Then the second vertex, going around "clockwise" (let's say the octagon was represented that way) is among $3,4$ or $5$ (if we put one at $6$, the third vertex would be $7$ or $8$, which would give the triangle a side in common with the …
