What is the different formulas for interior angles of a polygon

The video tutorial covers the calculation of the sum of interior angles in polygons, using the formula (n-2) * 180, where n is the number of sides. It explains how to find one interior angle in regular polygons by dividing the sum by the number of sides. Examples of regular polygons, such as equilateral triangles and hexagons, are provided to illustrate the concepts. The importance of regularity in polygons for these calculations is emphasized.

What is the formula to calculate the sum of interior angles in a polygon?

• n * 360

• (n+2) * 180

• n * 180

• (n-2) * 180

How many sides does a polygon have if its interior angles sum up to 540 degrees?

• 3 sides

• 6 sides

• 4 sides

• 5 sides

In a regular polygon, how do you find the measure of one interior angle?

• Multiply the sum of angles by the number of sides

• 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

What is a characteristic of a regular polygon?

• All sides are different

• All sides and angles are equal

• All angles are different

• Only one angle is equal

If a regular hexagon has a total angle sum of 720 degrees, what is the measure of one angle?

• 180 degrees

• 60 degrees

• 90 degrees

• 120 degrees
