☆☆☆☆☆A septagon.
Heptagon
A regular nonagon is a shape with 9 equal sides, right? Well, with the equation (n-2)180, where n is the number of sides, you can find the sum of the interior angles. Then you divide that number by n to get the measure of each interior angle. You do the rest.

It is generally accepted to count only one vertex per side when calculating the sum of exterior angles. If this is what you mean, then for every convex polygon (all angles point away from center), the sum is always 360º.
However, you can also count two vertexes per side, so the sum would then be double, or 720º.

More like Z-.
A square does not have a larger exterior angle than an interior one - they are both 90 degrees. The ONLY regular polygon with the required property is an equilateral triangle.
