What is the definition of a regular polygon and how do you find the interior angles

The video tutorial explains the concept of regular polygons, focusing on triangles and quadrilaterals. It covers the types of triangles: equilateral, isosceles, and scalene, and how to calculate their angles. The tutorial also defines regular polygons as having equal side lengths and angles, and demonstrates how to calculate the sum of interior angles using the formula (n-2)*180, where n is the number of sides. The video emphasizes understanding the properties of regular polygons and their applications in geometry.

What is a characteristic of an equilateral triangle?

• All sides are different

• Two sides are equal

• One angle is obtuse

• All angles are equal

In an isosceles triangle, how many angles are equal?

• Two

• None

• One

• Three

What defines a regular polygon?

• All sides are different

• All angles are different

• Equal sides and angles

• Only angles are equal

What is the sum of the interior angles of a quadrilateral?

• 720 degrees

• 540 degrees

• 360 degrees

• 180 degrees

How do you find the measure of an individual angle in a regular quadrilateral?

• Divide 720 by 4

• Divide 360 by 4

• Divide 540 by 4

• Divide 180 by 4

What is the formula for the sum of interior angles of a polygon?

• n * 180

• (n - 2) * 180

• n + 180

• (n + 2) * 180

How do you calculate the measure of an individual angle in a regular polygon?

• Add the number of sides to the sum of angles

• Divide the sum of angles by the number of sides

• Subtract the number of sides from the sum of angles

• Multiply the sum of angles by the number of sides
