Question

If the smallest angle of rotation is 90° then the order of symmetry is?
a) 1 b) 3 c) 4 d) 2​

Answer 1

Answer:

If the smallest angle of rotation is 90° then the order of symmetry is 4.

Step-by-step explanation:

Given: The smallest angle of rotation is 90°.

Find: The order of symmetry.

The product of the angle and the order will be equal to 360°.

So,  90° × order = 360°

Order = 360/90 = 4

So, order of symmetry is 4.
