Question

Write the angle of rotation and order of rotational symmetry for the following 

​

Answer 1

$\sf:- \: \: \: {\red{Answer }}$

1. The angle of rotation for the rhombus is 180 degrees whereas the order of rotational symmetry of rhombus is 2.
2. The order of rotational symmetry of a square is, how many times a square fits on to itself during a full rotation of 360 degrees. Please look at the images of the square in the order A, B, C, D and E. A is the original image.
3. If we rotate a rectangle 90 degrees each time , we will notice that we are able to get the original shape twice. The first time we get the original image, we get it with a rotation of 180 degrees and the second time, we get it with a rotation of 360 degrees.

Answer 2

Answer:

The angle of rotation for the rhombus is 180 degrees whereas the order of rotational symmetry of rhombus is 2.

The order of rotational symmetry of a square is, how many times a square fits on to itself during a full rotation of 360 degrees. Please look at the images of the square in the order A, B, C, D and E. A is the original image.

If we rotate a rectangle 90 degrees each time , we will notice that we are able to get the original shape twice. The first time we get the original image, we get it with a rotation of 180 degrees and the second time, we get it with a rotation of 360 degrees.
