Six-sided facts worth noticing
A regular hexagon is especially useful because each interior angle measures one hundred twenty degrees and the shape can be divided neatly into six congruent equilateral triangles from its center.
Hexagons matter in geometry and applications because they sit at a sweet spot between simple symmetry and efficient tiling. That makes the regular case one of the most recognizable polygons beyond the square.
When you count a hexagon, start at one vertex and move around the entire boundary in one direction. Do not count a diagonal or an interior line as an extra side. In the regular case, the center-to-vertex segments divide the shape into six small equilateral triangles, which explains much of its clean symmetry.
A regular hexagon is also a useful tessellation shape because six copies can meet around a point without leaving a gap. That application comes from its 120-degree interior angles, not from the word hexagon alone.
If the six sides are unequal, the polygon still has a 720-degree total inside. What changes is the distribution of the angle measures, not the side-count identity. This distinction is useful whenever a diagram is not drawn as a perfect regular hexagon.
- A hexagon is a polygon with six sides.
- A hexagon has six sides, six vertices, and an interior angle sum of seven hundred twenty degrees.
- Each interior angle of a regular hexagon is one hundred twenty degrees.
- A regular hexagon can be partitioned into six congruent equilateral triangles from the center.
