How to determine the difference between interior and exterior angles

The video tutorial explains how to determine exterior angles by first understanding interior angles. It covers the method of extending a polygon's side to create an exterior angle and differentiates between interior and exterior angles. The tutorial also touches on the significance of exterior angles in geometry.

What is the formula to calculate the sum of interior angles in a polygon?

• (number of sides + 1) * 180

• (number of sides - 1) * 180

• (number of sides + 2) * 180

• (number of sides - 2) * 180

How can you create an exterior angle in a polygon?

• By bisecting an interior angle

• By removing a side of the polygon

• By adding a new side to the polygon

• By extending a side of the polygon

What happens when you extend a side of a polygon?

• The polygon becomes a different shape

• The interior angles increase

• An exterior angle is formed

• The number of sides decreases

Which of the following is true about exterior angles?

• They are formed by extending a side of a polygon

• They are always larger than interior angles

• They are equal to the interior angles

• They are formed by bisecting an interior angle

Why is it important to understand exterior angles?

• They are not important in geometry

• They are used to calculate the area of polygons

• They help in solving geometric problems

• They determine the color of a polygon
