1. What is the Diagonal across Three Sides of Hexadecagon?

The Diagonal across Three Sides of a Hexadecagon is the straight line joining two non-adjacent vertices across three sides of the regular 16-sided polygon. It represents one of the various diagonal measurements possible within a hexadecagon.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

\[ Diagonal_{3} = Diagonal_{2} \times \frac{\sin\left(\frac{3\pi}{16}\right)}{\sin\left(\frac{\pi}{8}\right)} \]

Where:

\( Diagonal_{2} \) — Diagonal across two sides of the hexadecagon (m)
\( \pi \) — Mathematical constant approximately equal to 3.14159
\( \sin \) — Trigonometric sine function

Explanation: This formula derives from the geometric properties and trigonometric relationships within a regular hexadecagon, utilizing the sine function to establish the proportional relationship between diagonals across different numbers of sides.

3. Importance of Diagonal Calculation

Details: Calculating diagonals in regular polygons is essential for geometric analysis, architectural design, and various engineering applications where precise measurements of polygonal shapes are required.

4. Using the Calculator

Tips: Enter the diagonal across two sides value in meters. The value must be positive and greater than zero. The calculator will compute the corresponding diagonal across three sides using the trigonometric relationship.
