I assume you meant:
...we take the components of a vector along i and j to be equal
We assume North-East direction is equal North (j) and East (i). Similarly particle travelling East is travelling in 1i and 0j.
It is all assumption - but convenient assumption. You may choose to have any set of perpendicular directions as i and j (in this case North and East).
