There (not their) are 10 angles.
A decagon has 10 angles (and sides)
There are no right angles in a regular decagon. On a regular decagon, the angles are 144 degrees, where as right angles are ninty.
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 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 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.
None.
