**1)** The first and main property that is derived from the name itself is that it has six sides and all are equal in length.

**2)** Since all sides are equal, therefore all angles in a regular hexagon are equal.

**3)** All exterior angles of a regular hexagon are of same measure which is equal to $60^{\circ}$. This can be evaluated from the fact that all exterior angles of a polygon add up to $360^{\circ}$ and one angle will thus be given by dividing it by number of sides.

**4)** Every interior angle of a regular hexagon is of measure $120^{\circ}$. This can be evaluated using the exterior angle measure and the straight line angle property.

**5)** Sum of the interior angles of a regular hexagon is $720^{\circ}$.

**6)** The triangles that are formed in the hexagon by joining all the vertices with the center of the hexagon are all equilateral and are equal in size.

**7)** There are nine diagonals in a regular hexagon and all are of equal length.

**8)** The apothem (Ap) of a regular hexagon can be calculated using the formula below, if ‘$l$’ which is the length of the line joining the vertex and the center of the hexagon are known.

$Ap$ = $\sqrt{(l^{2} – (\frac{l}{2})^{2})}$ = $(\sqrt{3})\ \times$ $\frac{l}{2}$
