Posted In: Mathematics

In Euclidean plane geometry, a Regular Hexagon is a Hexagon having all sides are the same length (congruent) and all interior angles are the same size (congruent).

Regular Hexagon


Side: a
Internal angle: α
Slant height: m
Radius of circumscribed circle: R
Radius of inscribed circle: r
Perimeter: L
Semiperimeter: p
Area: S

  1. $α=120°$
  2. $r=m={a√3}/2$
  3. $R=a$
  4. $L=6a$
  5. $S=pr={a^2 3√3}/2,$
    where $p=L/2$
