Unlock the geometry of seven-sided polygons with our easy-to-use Heptagon Calculator. Whether you're a student, architect, or designer, accurately determine the area, perimeter, and apothem of any regular heptagon. Simply input the side length or apothem to get instant, precise measurements for your projects and studies.
Formula:
For a regular heptagon, the key properties are calculated using the following formulas:
- Perimeter (P): `P = 7 × s`
- Apothem (a): `a = s / (2 × tan(π/7))`
- Area (A): `A = (7/2) × s × a`
Where:
- `s` = Side length of the heptagon
- `a` = Apothem (distance from the center to the midpoint of a side)
- `π` ≈ 3.14159265359 (mathematical constant Pi)
