Question

The interior angle of the regular pentagon below measures 108, and the pentagon has rotational symmetry. Which of the following is the measure of an interior angle after a 90 rotation around the point of symmetry?

Answer 1

Answer:

108

Step-by-step explanation:

Answer 2

The measure of interior angle after a 9$0^{o}$ rotation is 10$8^{o}$

What is pentagon?

In the pentagon, the sum of the interior angles is equal to 540°. If all the sides are equal and all the angles are of equal measure, then it is a regular pentagon. Otherwise, it is irregular. In the regular pentagon, each interior angle measures 108°, and each exterior angle measures 72°.

according to the question

After rotation the size of the interior angle stays the same.

10$8^{o}$ = 10$8^{o}$

Hence, the measure of interior angle after a 9$0^{o}$ rotation is 10$8^{o}$
