Some 20-gons will have only one: 360 degrees.

Some 20-gons will have 2 (180 deg), some will have 90 deg, 72 deg, 36 deg of 18 deg. It depends on the extent of irregularity of the polygon.

What are the angles of rotation for a 20-gon?

The angles of rotation for a regular 20-gon can be determined by dividing 360 degrees by 20, which equals 18 degrees. Therefore, the angles of rotation are multiples of 18 degrees: 0°, 18°, 36°, 54°, 72°, 90°, 108°, 126°, 144°, 162°, 180°, 198°, 216°, 234°, 252°, 270°, 288°, 306°, 324°, and 342°. Each of these angles represents a distinct rotation that maps the 20-gon onto itself.
