What is the difference between a regular and irregular polygon

The video tutorial explains the concepts of regular and irregular polygons, highlighting their characteristics such as equal or unequal side lengths and angles. It provides examples like equilateral triangles and squares for regular polygons and discusses how to identify irregular polygons. The tutorial also covers the calculation of the sum of interior angles and individual angle measurements in polygons, using formulas and examples for triangles, quadrilaterals, and pentagons.

What defines a regular polygon?

• Equal side lengths and different angle measures

• Different side lengths and equal angle measures

• Equal side lengths and equal angle measures

• Different side lengths and different angle measures

Which of the following is an example of a regular polygon?

• Scalene triangle

• Equilateral triangle

• Right triangle

• Isosceles triangle

What is a characteristic of an irregular polygon?

• All sides are equal

• It has only three sides

• All angles are equal

• Sides and angles are not all equal

How do you calculate the sum of interior angles in a polygon?

• (n - 2) * 180

• n * 180

• (n + 2) * 180

• n + 180

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

• 180 degrees

• 720 degrees

• 540 degrees

• 360 degrees

How many degrees is each angle in a regular pentagon?

• 108 degrees

• 90 degrees

• 120 degrees

• 60 degrees

What formula is used to find the measure of each angle in a regular polygon?

• (n + 2) * 180 / n

• 180 / (n - 2)

• n * 180 / (n - 2)

• (n - 2) * 180 / n
