Find the size of each exterior angle of a regular octagon.
Answer Details
A regular octagon has eight sides of equal length and eight equal exterior angles. To find the size of each exterior angle, we can use the fact that the sum of all exterior angles in any polygon is 360 degrees. Therefore, the size of each exterior angle in a regular octagon can be found by dividing 360 degrees by the number of exterior angles, which is 8.
Using a calculator, we get:
360 degrees / 8 = 45 degrees
Therefore, the size of each exterior angle in a regular octagon is 45 degrees. The correct option is 45o.
