How to find the individual measurement of an interior angle for a regular dodecagon

The video tutorial covers the calculation of interior angles in regular polygons, focusing on a dodecagon. The teacher explains the properties of regular polygons, introduces relevant formulas, and demonstrates the calculation of an individual interior angle for a dodecagon, which is found to be 150 degrees.

What is the main task introduced by the teacher in the video?

• Determining the measure of each interior angle of a regular polygon

• Finding the perimeter of a polygon

• Calculating the area of a dodecagon

• Identifying the number of sides in a hexagon

What is a key characteristic of a regular dodecagon?

• It has more than twelve sides

• It is a three-dimensional shape

• It has twelve equal sides and angles

• It has unequal sides

Which formula is used to find the measure of an individual angle in a regular polygon?

• Individual angle = (n - 2) * 180 / n

• Circumference = 2 * π * radius

• Perimeter = 2 * (length + width)

• Area = base * height / 2
