A decagon has 10 angles (and sides)

a decagon
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
''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°
None.
Not normally but if it was an irregular decagon then it's quite possible.
A decagon has 10 angles (and sides)
3 but im not 100% sure
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.
There (not their) are 10 angles.
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 regular or an irregular decagon is a ten sided shape that has 10 interior angle that add up to 1440 degrees.
A decagon has 10 sides. It also have 10 angles.
A decagon will always have its interior angles measure 1480
A decagon can have acute angles.
