In geometry, any polygon with six sides and six angles and six vertices is called as Hexagon. The sum of angles in a Hexagon is 720°.
Hexagon Picture
In real life, Hexagon shape can be seen in ice crystals by which snow is formed. Some snowflakes have the shape of regular hexagons. The cells of beehive seen in honeycombs are also hexagonal in shape. The number of diagonals in a polygon is given by the formula $\frac{n(n-3)}{2}$. Hence the number of diagonals that can be drawn in a Hexagon are 9 since n = 6 in a Hexagon.

A Hexagon having all sides of equal length and equal angles is called regular Hexagon.

Regular Hexagon

The figure above shows a regular Hexagon. Each of its internal angles is equal to 120°. The formula to find an interior angle of an n-sided polygon is given by $\frac{[(n-2) \times 180]}{n}$. In a polygon, the central angle is the angle made at the centre of the polygon by any two adjacent vertices and is given by the formula $\frac{360^o}{n}$. Thus the central angle measure of a regular hexagon is 60 °.

The number of triangles that can be drawn by drawing the diagonals from a given vertex in general is given by n - 2 and so we can draw 4 triangles in a regular hexagon.
