- acute- less than 90 degrees
- right- exactly 90 degrees, creates an L shape
- obtuse - more than 90 degrees but not at 180 degrees
- straight angle - exactly 180 degrees, a straight line
- reflex angle - between 180° and 360°
So really there are 5 named categories. But in a polygon, there would never exist a straight angle, because then the two 'sides' would just become 1 side.
