What polygon that has 10 raise to 100 sides?

Answer 1

Polygons with more than 12 sides are often referred to by the expression n-gon, where n is the number of sides. For example, a 20-sided figure may be called a "20-gon" and a 100-sided figure may be referred to as "100-gon".

Because 10^100 is a special number, a "googol", a polygon with that number sides could be called a "googol-gon".

Such a figure would have interior angles that were almost, but not quite 180 degrees.
