Yes, a star, no matter how many sides it has, is still a polygon. Check these sites.

And yes, a five-pointed star, like the ones in the U.S. flag, is one type of decagon.
A star is not considered a polygon. A polygon is a closed two-dimensional figure with straight sides. It can have any number of sides, as long as the sides are straight and it is closed.
In the case of a star, it typically has five points (commonly referred to as a five-pointed star). Each point of a star can be connected to the adjacent points by straight lines, but the shape as a whole is not considered a polygon because it has intersecting lines and is not a closed figure.
So, a star does not have a specific number of sides like a polygon would.
