Question

The interior angle of the regular octagon below measures 135º, and the

octagon 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

the answer is D on e2020

Explanation:

Answer 2

D

Explanation:

Since the shape won't change, it won't deform, nothing will happen to the interior angle.

This figure is symmetric and not deformed, so the measure of the interior angle won't change no matter how many times you rotate it.

So the interior angle would still be 135º.

Correct answer D
