What is a 10 sided shape called?
In geometry, a polygon is a closed two-dimensional figure with three or more straight lines.
Answer: A 10 sided polygon is called a decagon.
The Greek word ‘Polygon’ consists of poly meaning ‘many’ and gon meaning ‘angle.’
A decagon is a ten-sided polygon with ten vertices and ten angles.
Interior angle of any regular polygon = 180 [(n - 2)/n]
Interior angle of a regular decagon = 180 (10 - 2)/10 = 144°
The sum of all the interior angles of a regular decaagon is 1440°.
Thus, a 10 sided polygon is called a decagon.
