A regular or an irregular decagon is a ten sided shape that has 10 interior angle that add up to 1440 degrees.
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
A decagon is a 10 sided polygon Exterior angles add up to 360 degrees Interior angles add up to 1440 degrees It has 35 diagonal A decagon can have a regular or an irregular shape
A regular decagon has 10 equal sides.

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?
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.
10000000000 * * * * * The central angle in any closed shape must be 360 degrees. This is the measure of the angles about a point.
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
A decagon has 10 angles (and sides)

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 ten vertices.
A regular decagon, or 10-sided polygon, has interior angles of 144
There (not their) are 10 angles.
