Question

For a regular 20-sided polygon, what is the degree of rotation?

Question 1 options:

18°


324°


162°


180°

Answer 1

The correct choice is the first one : 18

Answer 2

Answer: The correct option is (A) 18°.

Step-by-step explanation: We are given to find the degree of rotation for a regular 20-sided polygon.

We know that

if a regular polygon has n sides, then its degree of rotation is given by

`d=(360^\circ)/(n).`

For the given regular polygon, we have

n = 20.

Therefore, the degree of rotation of the given polygon is given by

`d=(360^\circ)/(20)=18^\circ.`

Thus, the required degree of rotation is 18°.

Option (A) is CORRECT.
