Comparing Interior Angles of a Pentagon

Consider a regular pentagon (a five-sided polygon) with each side measuring 5 cm. In a regular polygon, all sides are equal in length, and all interior angles are equal.

To find the sum of the interior angles of a polygon, you can use the formula:

$$ S = (n - 2) \times 180 $$

where n is the number of sides. For a pentagon, determine the sum of the interior angles and the measure of each interior angle.

Based on your calculations, answer the following:

Quantity A: The sum of the interior angles of the pentagon.

Quantity B: The measure of one interior angle of the pentagon.
