a line on the surface of the earth cutting all meridians at the same angle –

Q2. Consider the following statements on rhumb lines: *

A rhumb line and a great circle will never have the same true direction for some distance

The true direction of a rhumb line on northern hemisphere will increase in true direction, while on southern hemisphere it will decrease

Most rhumb lines will run as spirals from the one pole to another

A rhumb line will never cross a great circle

Most rhumb lines will run as spirals from the one pole to another –
