In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees. The regular icosagon has Schläfli symbol {20}, and can also be constructed as a truncated decagon, t {10}, or a twice-truncated pentagon, tt {5}.

An icosagon is a shape with 20 sides and 20 corners. It has interior angles of 162 and exterior angles of 18. The regular icosagon has Schläfli symbol {20}, and can also be constructed as a truncated decagon, t {10}, or a twice-truncated pentagon, tt {5}. The amount of space a regular icosagon takes up is. a is the length of one of its sides.

An icosagon is a 20-sided polygon with 20 angles. The regular icosagon is the Petrie polygon for a number of higher-dimensional polytopes, shown in orthogonal projections in Coxeter planes:

2024年11月23日 · In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees. The regular icosagon has Schläfli symbol {20}, and can also be constructed as a truncated decagon, t {10}, or a twice-truncated pentagon, tt {5}.

An icosagon is a polygon with exactly 20 20 sides (and internal angles). Results about polygons can be found here. The word icosagon derives from the Greek eíkosi (εἴκοσι), meaning twenty, and gon, deriving from the Greek for corner.
