Determine the measure of each exterior angle of a regular octagon

The video tutorial explains how to find the measure of each exterior angle in a regular polygon, specifically an octagon. It emphasizes that the sum of all exterior angles in any polygon is always 360 degrees. The tutorial guides through the process of calculating the measure of one exterior angle by dividing the total sum by the number of sides. It also clarifies the concept of regular polygons, where all angles and sides are equal, and demonstrates the calculation using an octagon as an example.

What is the sum of the exterior angles of any polygon?

• 720 degrees

• 180 degrees

• 360 degrees

• 540 degrees

In a regular polygon, how are the exterior angles related?

• They are all different

• They are all equal

• They are twice the interior angles

• They sum up to 180 degrees

Why are the exterior angles of a regular polygon equal?

• Because the sum of the exterior angles is 180 degrees

• Because the interior angles are equal

• Because the sides are of different lengths

• Because the interior angles are different

How do you find the measure of one exterior angle in a regular polygon?

• Subtract the number of sides from 360

• Multiply the number of sides by 360

• Divide 360 by the number of sides

• Add the interior angles and divide by the number of sides

If a regular polygon has 8 sides, what is the measure of one exterior angle?

• 30 degrees

• 40 degrees

• 45 degrees

• 50 degrees
