1. What is the Long Diagonal of Octagon?

The Long Diagonal of Octagon is the length of longest diagonals or the line joining any pair of opposite vertices of the Regular Octagon. It represents the maximum distance between any two vertices in a regular octagon.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sqrt{4 + (2 \times \sqrt{2})} \) — Constant factor (approximately 2.61312593)
• Edge Length of Octagon — Length of any edge of the Regular Octagon (in meters)

Explanation: The formula calculates the longest diagonal by multiplying the edge length by a constant derived from the geometric properties of a regular octagon.

3. Importance of Long Diagonal Calculation

Details: Calculating the long diagonal is crucial in geometry, architecture, and engineering for determining the maximum span of octagonal structures and for various design applications involving regular octagons.

4. Using the Calculator

Tips: Enter the edge length of the octagon in meters. The value must be positive and greater than zero for accurate calculation.
