Any hexagon has six sides.
No
It can be but need not be.
A convex hexagon is a six-sided polygon in which all interior angles are less than 180 degrees.
a polygon with 6 sides * * * * * The fact that is has six sides makes it a hexagon but that does not explain ""convex". A convex polygon is one in which none of the angles is a reflex angle. An alternative definition of convex is that a line joining any two points inside the hexagon is wholly inside the shape.

A convex hexagon is a plane shape bounded by six straight lines such that none of its interior angles is 180 degrees or greater.
A convex hexagon is a simple polygon whose interior is a convex set. It is a six-sided polygon, and it has no angles pointing inwards, meaning that no internal angles can be more than 180 degrees.
No.
A regular hexagon has zero right angles. An irregular convex hexagon could have 0-3.
