1. What is the Short Diagonal of Octagon?

The Short Diagonal of Octagon is the length of smallest diagonals or the line joining a vertex and any one of the vertices that coming next to the adjacent vertices of the first vertex of the Octagon. It is an important geometric property in octagonal shapes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sqrt{} \) — Square root function
• Inradius of Octagon — The radius of incircle of the Regular Octagon

Explanation: This formula calculates the short diagonal length based on the given inradius of a regular octagon, utilizing mathematical constants and square root functions.

3. Importance of Short Diagonal Calculation

Details: Calculating the short diagonal is crucial for geometric analysis, architectural design, and engineering applications involving octagonal structures. It helps in determining various properties and dimensions of octagonal shapes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a regular octagon?
A: A regular octagon is an eight-sided polygon where all sides are equal in length and all angles are equal in measure.

Q2: What is the inradius of an octagon?
