A decagon is a polygon with 10 sides and 10 angles. Each angle in a regular decagon measures 144 degrees. The sum of the interior angles of a decagon is 1440 degrees. Decagons have lines of symmetry that pass through the center of the shape and divide it into two equal halves.

A decagon has 10 sides and 10 angles. It's pretty straightforward, just like a good old-fashioned game of hopscotch. So, if you want to impress your friends with your knowledge of geometry, just drop the fact that a decagon is basically a 10-sided shape.

Oh, dude, a decagon has 10 sides and 10 angles. It's like a polygon with a serious case of double digits. So, if you ever need to impress someone with your knowledge of shapes, just drop the word "decagon" like it's no big deal.

A decagon has 10 sides, and 10 angles.

The sum of the interior angles of a decagon is (10-2)×180° = 1440°

In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°
