A septagon
well if you take octagon (8 sides) , in 3d shapes octagon is probably called octagonal prism. and the sides are actually called faces. AND a 7 sided shape , a heptagon, is called heptagonal prism
I assume you want the name of each shape, not just the generic polygon which refers to any multi-sided shape.5 sides - pentagon6 sides - hexagon7 sides - heptagon8 sides - octagon9 sides - nonagon10 sides - decagon
6 sides is a hexagon a shape with 7 sides is a heptagon don't get them mixed up and besides that question was already on wikianswers and it was answered
