Question

Through which angle of rotation does the image of a regular pentagon coincide with its preimage?

Answer 1

Answer:

The correct answer option is B. 72°.

Step-by-step explanation:

A polygon is said to be a regular polygon when all its sides and angles are equal.

So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.

When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.

Therefore, option B is the right choice.
