Understanding the Parameters

The Hendecagon Calculator works by computing various geometric properties of an eleven-sided polygon. Below is a detailed explanation of each parameter used in the calculations.

Edge Length (a)

The edge length (a) is the length of one side of the hendecagon. It is the most fundamental measurement, as many other values, including diagonals, perimeter, and area, depend on it.

Diagonal Across 5 Sides (d5)

The diagonal across 5 sides (d5) is the longest diagonal in the hendecagon. It connects two vertices that are five sides apart. This diagonal is useful in determining the overall structure and symmetry of the hendecagon.

Diagonal Across 4 Sides (d4)

The diagonal across 4 sides (d4) spans four sides between two non-adjacent vertices. This diagonal helps define internal angles and structural proportions within the hendecagon.

Diagonal Across 3 Sides (d3)

The diagonal across 3 sides (d3) connects two vertices that are separated by three sides. This diagonal is shorter than d5 and d4 but still plays a role in understanding the shape’s internal structure.

Diagonal Across 2 Sides (d2)

The diagonal across 2 sides (d2) links two vertices with a two-side separation. This is one of the shortest diagonals and is essential in understanding the internal arrangement of lines within the hendecagon.

Height (h)

The height (h) is the vertical distance from the base to the highest point of the hendecagon when it is positioned symmetrically. This measurement is useful in construction and design applications where vertical alignment is crucial.

Perimeter (p)

The perimeter (p) is the total length of all eleven sides of the hendecagon. It is calculated using the formula:

p = 11 × a

This value is particularly useful in applications where the outer boundary of the shape needs to be measured, such as fencing, tiling, or design layouts.

Area (A)

The area (A) represents the total space enclosed by the hendecagon. It is computed using the formula:

A = (11 × a²) / (4 × tan(π/11))

This measurement is important for estimating material usage in construction, design, and mathematical modeling.

Circumcircle Radius (rc)

The circumcircle radius (rc) is the radius of the circle that passes through all the vertices of the hendecagon. It is calculated using:

rc = a / (2 × sin(π/11))

This parameter is particularly useful in applications where the hendecagon must be inscribed in a circular boundary.

Incircle Radius (ri)

The incircle radius (ri) is the radius of the largest circle that can fit perfectly inside the hendecagon, touching all sides. It is computed as:

ri = a / (2 × tan(π/11))

This measurement is valuable in geometric optimization problems and design applications where internal spacing is critical.
