Question

find the angle of rotation if the order of rotational symmetry is 18

Answer 1

20'

plz mark me as brainliest

Answer 2

Answer:

20°

Step-by-step explanation:

The order of rotational symmetry means how much times the figure looks the same when it is rotated. For example order of rotation of square is 4 i. e. It will look 4 times similar when it is rotated.

Answer:

We know that angle of rotation

=360/order of rotation

Here the order of rotation is =18

So according to the formula the equation comes like

360/18

By dividing them we get the answer as:

=20°

Hence the angle of rotation is 20°

So finally,

Order of rotation =18

Angle.of rotation =20°
