Find the order of rotation if the angle of rotation is $60 °$ .

Open in App

Solution

We know that if the angle of rotation is $x °$ then the order of rotation will be = $\frac{360 °}{x °}$
As we have given angle of rotation is $90 °$ .
So using the above formula we have,
Order of rotation = $\frac{360 °}{90 °}$
= $4$
Hence, the order of rotation is $4$ .
