What are properties of hexagons?

An exagon is not a commonly known shape. It may possibly be a misspelling or a rare geometric term.

Assuming you meant "hexagons", here are some properties of hexagons:

1. Six sides: Hexagons have six straight sides.

2. Six angles: Hexagons have six interior angles, each measuring 120 degrees, making the sum of their angles 720 degrees.

3. Regular or irregular: Hexagons can be regular, with all sides and angles equal, or irregular, with different side lengths and/or angles.

4. Convex or concave: Hexagons can be convex, where all interior angles are less than 180 degrees, or concave, where at least one interior angle is greater than 180 degrees.

5. Symmetry: Regular hexagons possess rotational symmetry of order 6, meaning they can be rotated by multiples of 60 degrees and still appear the same.

6. Diagonals: Hexagons have nine diagonals (lines connecting non-adjacent vertices).

7. Tessellation: Hexagons are an efficient shape for tessellating (covering a plane with no gaps or overlaps) in combination with other hexagons.

8. Symmetrical division: By connecting some of its diagonals, a hexagon can be divided into three congruent parallelograms or six congruent triangles.
