Exploring Angles in Polygons

The video tutorial covers the concepts of regular polygons, focusing on calculating interior and exterior angles. It explains two methods for finding these angles and demonstrates their application through various examples. The tutorial also addresses complex problems involving polygons and provides strategies for solving them. Key concepts include the sum of angles in polygons, the relationship between interior and exterior angles, and practical problem-solving techniques.

What is the sum of the interior angles of a polygon divided into triangles?

• Number of triangles times 360

• Number of sides minus two times 180

• Sum of angles in one triangle plus the number of sides

• Sum of angles in one triangle times the number of triangles

What is the sum of the interior angles of a polygon with 20 sides?

• 3240 degrees

• 3060 degrees

• 3360 degrees

• 3180 degrees

How do you find the interior angle of a regular pentagon?

• Add 180 to each exterior angle

• Multiply the number of sides by 180

• Subtract the number of sides from 360

• Divide the sum of angles by 5

What is the method to calculate the interior angle of a polygon?

• (Number of sides + 2) * 180

• Number of sides * 180

• 360 divided by number of sides

• (Number of sides - 2) * 180, then divide by number of sides
