# How can I construct vector diagrams?

This could be drawn using carefully drawn vectors, drawn to an appropriate scale such as 1 cm = 20 km. This would mean drawing a 6.0 cm arrow, pointing east, then a 2.5 cm arrow drawn head-to-tail, pointing north (${90}^{o}$ angle between). The displacement is the straight-line, "as the crow flies" distance between the starting point and the ending point, which should work out to a 6.5 cm long arrow pointing approximately ${23}^{o}$ north of east.
