What do you call a shape with 7 or 9 points?

Triangle= trigon
Square= quadragon
5 points= hectagon
6 points= hexagon
7 points=?
8 points= octagon
9 points= ?
10 points= decagon

These are all concidered polygons right?

5 = pentagon
7 = heptagon
9 = nonagon

I've never seen trigon or quadragon used, though I suppose technically they are correct.
