Question

1. order? if no rotational symmetry, type n/a 11. magnitude? if no rotational symmetry, type n/a

Explanation:

Step1: Define rotational symmetry

Rotational symmetry is when a figure looks the same after a rotation.

Step2: Analyze the figure

The given figure (a square - like shape with diagonals) looks the same 4 times in a 360 - degree rotation. So the order of rotational symmetry is 4.

Step3: Calculate the magnitude

The magnitude of rotational symmetry is calculated as $\frac{360^{\circ}}{\text{Order}}$. Since the order is 4, the magnitude is $\frac{360^{\circ}}{4}=90^{\circ}$.

Answer:

1. 4
2. $90^{\circ}$
