Minitest 3 - question 2a

Physics Q&A
1

For minitest 3 (the one from this year), for question 2.a, it asks you to draw the first Brillouin zone. The solution however does not provide a drawing, and even when i look through the lecture notes I can’t really figure out how you’re supposed to draw these when you’re given a crystal lattice.
Would it be possible to show how a drawing is supposed to look?

The solution describes the answer in words quite precisely. For the description of the first Brillouin zone see here, and for the step-by-step description of how to draw it, see here.
