Decagon - Wikipedia In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon [1] The total sum of the interior angles of a simple decagon is 1440° A regular decagon has all sides of equal length and each internal angle will always be equal to 144° [1]
