A polygon is a closed geometric shape composed of straight sides. The number of sides in a polygon can vary, but it must have at least three sides, with each side connecting to the next at a vertex.

The number of diagonals in a polygon can be calculated using the formula (n * (n - 3)) / 2, where "n" represents the number of sides. This formula excludes the sides of the polygon itself, resulting in the count of diagonals.

Solution:
A pentagon has five sides, and to find the number of diagonals, we use the formula (n * (n - 3)) / 2, where "n" represents the number of sides.

For a pentagon, substituting the value of "n" into the formula:

(5 * (5 - 3)) / 2 = 5 diagonals.

So, a pentagon has 5 diagonals.
