1. What is 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 16-sided polygon. It represents one of the longer diagonals in a regular hexadecagon.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

\[ Diagonal = \frac{\sin\left(\frac{3\pi}{16}\right)}{\sin\left(\frac{\pi}{16}\right)} \times Side \]

Where:

\( \pi \) — Archimedes' constant (approximately 3.14159)
\( \sin \) — Sine trigonometric function
\( Side \) — Length of one side of the hexadecagon

3. Formula Explanation

Mathematical Basis: The formula derives from the trigonometric properties of regular polygons. The ratio of sines represents the relationship between the diagonal spanning three sides and the side length in a regular 16-sided polygon.

4. Using the Calculator

Instructions: Enter the side length of the hexadecagon in meters. The value must be positive. Click "Calculate" to get the diagonal measurement across three sides.

5. Frequently Asked Questions (FAQ)

Q1: What is a hexadecagon?
A: A hexadecagon is a polygon with 16 sides and 16 angles. When regular, all sides and angles are equal.

Q2: How many diagonals does a hexadecagon have?
A: A hexadecagon has 104 diagonals in total, with different lengths depending on how many sides they span.

Q3: What are the practical applications of this calculation?
A: This calculation is useful in geometry, architecture, and design where regular 16-sided shapes are used.

Q4: Can this formula be used for irregular hexadecagons?
A: No, this formula only applies to regular hexadecagons where all sides and angles are equal.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact for regular hexadecagons, with precision limited only by computational floating-point arithmetic.
