180 degrees
360 degrees would be one full rotation. 180 degrees would be a half rotation. 360+180=540 So it would be a rotation and a half.
90
90 degrees
A nonagon has 9 rotation symmetry
The answer is 210 degrees.
1/6 of half a rotation = 1/12 of a rotation = 1/12 of 360 degrees = 360/12 = 30 degrees.
90 degrees would be a half stroke.
180 degrees
360 degrees would be one full rotation. 180 degrees would be a half rotation. 360+180=540 So it would be a rotation and a half.
90 degrees * * * * * No! 1 rotation = 360 degrees so 21/4 rotations = 2.25*360 = 810 degrees
A semi-circle, half a circle, by definition is 180 degrees, half of a rotation. A whole circle has a whole rotation, which is 360 degrees.
1 rotation = 360 degrees 3/4 rotation = 270 degrees
A full rotation is a 360 degree rotation. A full circle is 360 degrees.
360 degrees
180 degrees is half a rotation so probably a half.
One full rotation is 360 degrees.
