Question

A circular wheel has 8 spikes.
What is the angle of rotation and the order of rotational symmetry?

Answer 1

here is your answer OK

it's very simple question...........

angle of rotation = 360/8 = 45 degree


It's answers is 45 becuase all angle 360and divide it by8 so a
360/8=45

Answer 2

Answer:

Angle of rotation is 45 and the order of rotational symmetry is 8 .

Step-by-step explanation:

Explanation:

Given, a circular wheel has 8 spikes.

• How many times a circle can fit on top of itself during a 360-degree revolution is the measure of a circle's rotational symmetry.
• The order of rotational symmetry refers to how many times a figure can rotate completely around itself.
• If a figure can return to its starting position after rotating completely or 360 degrees, it possesses rotational symmetry of order 1.

So the angle of rotation = $\frac{360}{8}$ =  45°

And the order of rotational symmetry is 8 because radius of wheel remain same of every rotation.

Final answer:

Hence, 45 is the angle of rotation and 8 is the order of rotational symmetry.
