$\\ \green {concept}$

• no of diagonal in a regular polygon of n sides is

$\\ \frac{n(n - 3)}{2}$

• Each interior angle of a regular polygon of n sides is

$\\ \frac{(n - 2) \: \: \pi}{n}$

• Each exterier angle of a regular polygon of n sides is

$\\ \frac{2\pi}{n}$

• trigonometry to find relation between sides

• area of triangle

$\\ \rightarrow \: \frac{1}{2} pq \sin(R) \:$

where small p, q are length of sides of corresponding angles

and capital R is angle Coroosponding to side of length r
