Question

why is order of rotation 2 of a rhombus?​

Answer 1

Answer:

The order of rotational symmetry can be defined as the number of times that shape appears exactly the same during a full 360° rotation. The order of rotational symmetry of a rhombus is 2.

Answer 2

Answer:

please mark my answer as brainliest plz

Step-by-step explanation:

The change after rotation is that vertex A becomes D and vice versa. Also, vertex B becomes C, and vice versa. So within 360∘ rhombus turns 2 times into itself as 360∘ divided by 180∘ is 2. And hence the order of rotational symmetry of the rhombus is 2.
