A decagon has 10 sides, and the whole polygon has 360 degrees, so each angle is 36 degrees.
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?
''Decagon'' is any polygon with ten sides and ten angles ''Regular decagon'' is a polygon with ten sides of equal length and all angles equal to 144°
The internal angles are 144 degrees. The external angles are 36 degrees.
1440
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
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.
Not normally but if it was an irregular decagon then it's quite possible.
A decagon has ten vertices.
There (not their) are 10 angles.
