A turn through 90 degrees.
Rotation is a vector having a direction and magnitude.

A 90 degree rotation is a quarter of a turn.
Hint: One rotation is 360 degrees.quarter = 1/4360 / 4 = 90Ninety degrees is a quarter of a rotation
the rotation of earth
1 rotation = 360 degrees 3/4 rotation = 270 degrees
90
180
One quarter of a day (24 hours), or 6 hours.
270 degrees
There are 270 degrees in 3/4 of a rotation
I'm guessing a quarter of a rotation of a circle would be 90 degrees (360/4) so two times would be.. 180? :)
180 degrees
750
