Step 1: Understanding the Concept:
The sum of interior angles in a polygon depends on the number of sides (\(n\)).
Step 2: Key Formula or Approach:
The formula for the sum of interior angles is:
\[ \text{Sum} = (n - 2) \times 180^\circ \]
Step 3: Detailed Explanation:
A pentagon has 5 sides, so \(n = 5\).
Plugging the value into the formula:
\[ \text{Sum} = (5 - 2) \times 180^\circ \]
\[ \text{Sum} = 3 \times 180^\circ \]
\[ \text{Sum} = 540^\circ \]
Each individual interior angle in a "regular" pentagon would be \(540^\circ / 5 = 108^\circ\).
Step 4: Final Answer:
The sum of interior angles of a pentagon is 540\(^\circ\).
