A regular or an irregular decagon is a ten sided shape that has 10 interior angle that add up to 1440 degrees.
The 10 interior angles of a decagon add up to 1440 degrees
A decagon has 10 sides and 10 angles.
decagon
Oh, dude, a decagon has 10 sides, right? So, each angle in a regular decagon measures 144 degrees. Now, a right angle is 90 degrees, so technically, there are zero right angles in a decagon. But hey, who's counting, right?
None.
A decagon has 10 angles (and sides)
A decagon can have acute angles.
It depends on whether or not the decagon is a perfect decagon or a complex decagon. However, a perfect decagon has no acute angles.

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°
A regular or an irregular decagon is a ten sided shape that has 10 interior angle that add up to 1440 degrees.
A decagon has ten vertices.
There (not their) are 10 angles.
