What is the formula to find the measure of one interior angle

The video tutorial explains how to calculate the sum of interior angles in a polygon using the formula (n-2) * 180, where n is the number of sides. It further discusses how to find the measure of one interior angle in a regular polygon by dividing the sum by the number of sides. The tutorial emphasizes the importance of the polygon being regular, meaning all angles are equal, for this calculation. The video concludes with a recap of the formula and a quick example.

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

• n * 180 degrees

• (n-2) * 180 degrees

• (n+2) * 180 degrees

• n * 360 degrees

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

• Add the number of sides to the sum of the interior angles

• Multiply the sum of the interior angles by the number of sides

• Divide the sum of the interior angles by the number of sides

• Subtract the number of sides from the sum of the interior angles

Why must a polygon be regular to find the measure of one interior angle?

• Because it is a closed shape

• Because it has more than four sides

• Because all angles must be equal

• Because it has equal sides

If a polygon has 5 sides, what is the measure of one interior angle?

• 120 degrees

• 72 degrees

• 90 degrees

• 108 degrees

For a quadrilateral, what do you divide the sum of the interior angles by to find one angle?

• 6

• 4

• 3

• 5
