Introduction: There are four main directions - East, West, North and South, as per the convention we generally take
upward direction of a paper as north direction and remaining directions as shown below:-
Other than 4 main direction there are four cardinal directions - North-East (N-E the direction exactly between North
and East), North-West (N-W the direction exactly between North and West), South-East (S-E the direction exactly
between South and East), and South-West (S-W the direction exactly between South and West) as shown below:
The main formula for Direction questions is Pythagoras Theorem.

As per the Pythagoras theorem a + b = c 2
Some Pythagorean triplets are:
3, 4, 5 and its multiples,
