Does parallel line which runs from east-west directions helps to measure latitude true or false

It is True.

The imaginary lines circling the globe in an east-west direction are called the lines of latitude (or parallels, as they are parallel to the equator). They are used to measure distances north and south of the equator. The lines circling the globe in a north-south direction are called lines of longitude (or meridians).
