Isaac draws a regular octagon and rotates it about its center.
Which angle measures can Isaac rotate the regular octagon through to map it onto itself?
Select each correct answer.
30°
45°
90°
120°
135°
180°

The sum of angles in a regular octagon is
180*(8 - 2) = 1080°.
Each angle of the octagon is 1080/8 = 135°.
There are 8 equal central angles to each vertex.
Each central angle is 360/8 = 45°

Answer:
Therefore the octagon will map onto itself if it is rotated by its center through these angles:
45°
90°
135°
180°
