1. What is the Diagonal Across Five Sides of Dodecagon?

The diagonal across five sides of a dodecagon is a straight line joining two non-adjacent vertices that spans across five sides of the regular twelve-sided polygon.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sqrt{3} \) — Square root of 3 (approximately 1.732)
• \( Side\ of\ Dodecagon \) — Length of one side of the dodecagon

Explanation: This formula calculates the length of the diagonal that spans across five sides of a regular dodecagon based on its side length.

3. Importance of Diagonal Calculation

Details: Calculating diagonals in geometric shapes is important for various applications in mathematics, engineering, architecture, and design where precise measurements of polygonal structures are required.

4. Using the Calculator

Tips: Enter the side length of the dodecagon in meters. The value must be a positive number greater than zero.

5. Frequently Asked Questions (FAQ)
