How to find the measure of one exterior angle given the number of sides ex 1

The video tutorial explains how to find the measure of each interior and exterior angle of a triangle. It introduces two methods: one using the sum of exterior angles, which is always 360 degrees for any polygon, and another using the relationship between interior and exterior angles, which are supplementary. Both methods are demonstrated to arrive at the same result, providing flexibility in approach depending on the learner's preference.

What is a regular polygon?

• A polygon with neither sides nor angles equal

• A polygon with all sides and angles equal

• A polygon with all sides equal but angles different

• A polygon with all angles equal but sides different

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

• 180 degrees

• 360 degrees

• 540 degrees

• 720 degrees

How do you calculate the measure of each exterior angle in a regular polygon?

• Divide 180 degrees by the number of sides

• Multiply 360 degrees by the number of sides

• Divide 360 degrees by the number of sides

• Multiply 180 degrees by the number of sides

What is the relationship between an interior angle and its corresponding exterior angle in a polygon?

• They are unrelated

• They are supplementary

• They are complementary

• They are equal

If an interior angle of a regular triangle is 60 degrees, what is the measure of its exterior angle?

• 60 degrees

• 90 degrees

• 120 degrees

• 150 degrees
