Identify hexagons

A hexagon is a closed, two-dimensional shape with exactly six straight sides and six vertices (corners); its sides and angles need not be equal, and its orientation, size, or appearance may vary. This understanding distinguishes hexagons from shapes with different numbers of sides or curved boundaries and supports later classification, composition, and analysis of polygons.

Detailed Explanation: Identify hexagons

A hexagon is a closed shape with exactly 6 straight sides and 6 corners (vertices).

To identify one:

  1. Make sure the shape is closed.
  2. Check that all its sides are straight.
  3. Count the sides. If there are exactly 66, it is a hexagon.
  4. Count the corners. There should also be 66.

Example

Look at a shape with corners labeled (A,B,C,D,E,)(A, B, C, D, E,) and FF:

  • AA to BB is side 11.
  • BB to CC is side 22.
  • CC to DD is side 33.
  • DD to EE is side 44.
  • EE to FF is side 55.
  • FF back to AA is side 66.

The shape is closed, all 6 sides are straight, and it has 6 corners. Therefore, it is a hexagon.

The sides do not have to be the same length, and the hexagon can be turned in any direction.
