Question

Can anyone explain me the question?​

Answer 1

Answer

It does not look the same after a rotation of 45 ∘

It requires a rotation of 90 ∘

So it looks the same after rotations of 90 ∘

,180 ∘ ,270 ∘ and 360 ∘

takes it back to its original position.

So the order of rotational symmetry is 4

Answer 2

Answer:

90°

Explained :

• Order of rotation=36O°
• Angle of rotation=360°➗4

= 90°

• So , the rotational symmetry of the figure is 90°.
