1. What is Diagonal Across Two Sides of Decagon?

The diagonal across two sides of a decagon is a straight line joining two non-adjacent vertices that are separated by two sides. It's an important geometric measurement in regular decagons.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( d2 \) — Diagonal across two sides
• \( A \) — Area of the decagon
• \( \sqrt{5} \) — Square root of 5 (approximately 2.23607)

Explanation: This formula calculates the diagonal length based on the area of a regular decagon, using mathematical constants specific to decagonal geometry.

3. Importance of Diagonal Calculation

Details: Calculating diagonals in polygons is essential for various geometric applications, architectural design, and understanding the spatial properties of regular shapes.

4. Using the Calculator

Tips: Enter the area of the decagon in square meters. The value must be positive and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)
