What is the sum of the interior angle measures of a pentagon?

To find the sum of the interior angle measures of a pentagon, you can use the formula:

Sum of interior angles = (n - 2) * 180 degrees

In this formula, "n" represents the number of sides of the polygon. For a pentagon, "n" is equal to 5.

So, using the formula, we can calculate the sum of the interior angles of a pentagon as follows:

Sum of interior angles = (5 - 2) * 180 degrees
= 3 * 180 degrees
= 540 degrees

Therefore, the sum of the interior angle measures of a pentagon is 540 degrees.
