A stop sign is in the shape of a regular octagon. What is the measure of each exterior angle?
(1 point)
• 40°
• 45°
• 50°
55°
The sum of the measures of the exterior angles of any polygon is always 360°. Since a stop sign has 8 exterior angles, we can divide 360° by 8 to find the measure of each angle.
360° / 8 = 45°
Therefore, the measure of each exterior angle of a stop sign is 45°.
