View the calculated area, perimeter, apothem, circumradius, and diagonal length.

Formula

Area = (3√3/2) × s²

Perimeter = 6s

Apothem = (√3/2) × s

Circumradius = s (for regular hexagon)

Where:

  • s = Side length
  • Apothem = Distance from center to midpoint of a side
  • Circumradius = Distance from center to vertex
  • For regular hexagon: circumradius = side length

Example: Calculate hexagon properties for side length = 10

Area = (3√3/2) × 10² = (3√3/2) × 100 = 150√3 ≈ 259.81 square units

Perimeter = 6 × 10 = 60 units

Apothem = (√3/2) × 10 = 5√3 ≈ 8.66 units

Understanding Regular Hexagons

A regular hexagon is a six-sided polygon with all sides equal and all angles equal (120°). Key properties:

  • Six Sides: All sides have equal length
  • Six Angles: Each interior angle = 120° (sum = 720°)
  • Equilateral Triangles: Can be divided into 6 equilateral triangles
  • Tessellation: Hexagons can tile a plane perfectly (honeycomb pattern)
  • Symmetry: Has 6-fold rotational symmetry
  • Efficient Packing: Hexagonal arrangement is most efficient for packing circles

Real-World Applications

Honeycomb: Bees create hexagonal cells because hexagons use the least wax to create the most storage space. This is the most efficient shape for tiling.

Engineering: Hexagonal bolts and nuts are common because the hexagon shape provides good grip and is easy to manufacture. Many mechanical components use hexagonal designs.

Architecture: Hexagonal tiles are popular for flooring. The hexagonal shape creates interesting patterns and efficient use of space.

Chemistry: Many crystal structures have hexagonal arrangements. Carbon atoms in graphene form hexagonal lattices.

Frequently Asked Questions

What is a regular hexagon?

A regular hexagon is a six-sided polygon with all sides equal in length and all interior angles equal to 120°. It's a highly symmetric shape with 6-fold rotational symmetry.

How do you calculate hexagon area?

For a regular hexagon, area = (3√3/2) × s², where s is the side length. This formula comes from dividing the hexagon into 6 equilateral triangles.

What is the apothem of a hexagon?

The apothem is the distance from the center of the hexagon to the midpoint of any side. For a regular hexagon, apothem = (√3/2) × side length.

Why do bees use hexagonal cells?

Hexagons are the most efficient shape for tiling a plane with equal-sized cells. They use the least material (wax) while maximizing storage space, making them perfect for honeycomb construction.

Can hexagons tile a plane?

Yes! Regular hexagons are one of only three regular polygons that can perfectly tile a plane (along with squares and equilateral triangles). This is why they appear in honeycombs and many natural patterns.

What's the relationship between hexagon and equilateral triangle?

A regular hexagon can be divided into 6 equilateral triangles by drawing lines from the center to each vertex. Each triangle has side length equal to the hexagon's side length.

How many diagonals does a hexagon have?

A hexagon has 9 diagonals. The formula for diagonals in an n-sided polygon is n(n-3)/2. For hexagon: 6(6-3)/2 = 9.
