Question

Which of the following are magnitudes for rotational symmetry of the rectangle below about the marked point?

​

Answer 1

B

Explanation:

Answer 2

The answer is B.180°.

Explanation:

The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.

In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.

Therefore, the only option that applies is B.180°
