An octagon may have 1, 2, 4 or 8 angles of rotation.
A circle has 360 degrees because angles are measured in degrees and and a full rotation of an angle is 360 degrees.

The exterior angles of any polygon always add up to 360 degrees because there are 360 degrees in a full rotation.
A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.

In a circle no, in a square yes.
An octagon may have 1, 2, 4 or 8 angles of rotation.
Angles are measured in degrees, minutes and seconds A full rotation measures 360 degrees
It was the ancient Babylonians and Greeks who classified angles into degrees out of 360 degrees which is full rotation of circle.
A circle has 360 degrees because angles are measured in degrees and and a full rotation of an angle is 360 degrees.
The three transformation in angles are translation , rotation , reflection .
1 complete rotation = 360o 1 right angle = 90o 360o ÷ 90o = 4 There are 4 right angles in 1 complete rotation.

Four times - each at 90 degree angles.
