1. What is the 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:

• \( Height \) — Height of the decagon (m)
• \( \sqrt{5} \) — Square root of 5 (approximately 2.23607)

Explanation: This formula calculates the diagonal length across two sides based on the height of a regular decagon, using mathematical constants derived from the geometry of regular polygons.

3. Importance of Diagonal Calculation

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

4. Using the Calculator

Tips: Enter the height of the decagon in meters. The value must be positive and greater than zero. The calculator will compute the diagonal length across two sides.
