What is the formula to calculate the sum of the interior angles of an n-sided polygon?

• (n-2) × 180°

• n × 180°

• (n+2) × 180°

• (n-1) × 180°

The measure of each interior angle in a regular n-sided polygon can be calculated using which of the following formulas?

• (n-2) × 180° / n

• n × 180° / (n-2)

• (n+2) × 180° / n

• n × 360° / 2

The sum of any exterior angle of a polygon is:

• 90°

• 180°

• 360°

• It depends on the number of sides
