Understanding Hexagons

A regular hexagon is a six-sided polygon with all sides and interior angles equal. It has many interesting geometric properties that make it useful in mathematics, nature, and design.

Key Properties
  • Interior Angles: Each interior angle of a regular hexagon is 120°
  • Exterior Angles: Each exterior angle is 60°
  • Diagonals: A hexagon has 9 diagonals
  • Sum of Interior Angles: 720° (n-2) × 180° where n = 6
  • Central Angle: 60° (360° ÷ 6)
  • Symmetry: 6 lines of symmetry
Applications

Hexagons are found in many real-world applications:

  • Honeycombs in beehives (efficient use of space and materials)
  • Hexagonal tiling in floor designs and mosaics
  • Molecular structures in organic chemistry
  • Nuts and bolt heads (provides better grip)
  • Hexagonal pencils (prevents rolling and provides better grip)
  • Snowflakes (hexagonal crystal structure)

Perimeter: \( P = 6s \)

Area: \( A = \frac{3\sqrt{3}}{2}s^2 \)

Inradius: \( r = \frac{\sqrt{3}}{2}s \)

Circumradius: \( R = s \)

Height: \( h = \sqrt{3}s \)
