How many sides has a octagon?
8Octagon / Number of edges
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}.

How do you name a polygon with 21 99 sides?
Di, tri, tetra, penta, and so on. We are familiar with these prefixes as they are used in a variety of mathematical—and even scientific—subjects. But polygons with 21-99 sides have a different naming system. First, we use a prefix for the tens (such as triaconta—30).
