A shape with 80 sides is called an octacontagon. In geometry, it is classified as a polygon with 80 edges and 80 vertices. The term comes from the Greek words "octa" meaning eight and "contagon" meaning sides, reflecting its complex structure. Octacontagons are often studied in advanced geometry and can be regular or irregular depending on the lengths of their sides and angles.
