Complete step-by-step answer:
In geometry a Decagon is a ten-sided polygon or 10-gon as shown in figure.
A regular decagon has all sides of equal length and each internal angle will always be equal to as shown in figure.
So the Decagon has 10 sides.
So, this is the required answer.
Hence option (D) is correct.
