Fundus angles are benchmark angle
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.
An octagon may have 1, 2, 4 or 8 angles of rotation.

The angle of rotation of a square refers to the degrees it can be rotated around its center without changing its appearance. A square can be rotated by 90 degrees, 180 degrees, 270 degrees, or 360 degrees and still look the same. Therefore, the angles of rotation that maintain the square's symmetry are multiples of 90 degrees.

The three transformation in angles are translation , rotation , reflection .
90 degrees 180 degrees 270 degrees 360 degrees!
1 complete rotation = 360o 1 right angle = 90o 360o ÷ 90o = 4 There are 4 right angles in 1 complete rotation.

A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.
