Understanding Apothem

Basic Definition

Apothem = s/(2 * tan(180°/n))

where s = side length, n = number of sides

Key Properties

  • Perpendicular to polygon side
  • Connects center to midpoint
  • Equal lengths in regular polygons

Area Calculation

  • Area = (perimeter × apothem)/2
  • Efficient area computation
  • Alternative to triangulation

Relationships

  • Radius-Apothem ratio
  • Side length correlation
  • Angular dependencies
