You should commit to memory the sides and angles of two simple triangles:
  1. 1.

    half of a unit square, formed by a diagonal line, gives a 45°, 45°, 90° triangle with sides 1,1,\(\sqrt 2 \)

  2. 2.

    half of an equilateral triangle with side length 2 gives a 30°, 60°, 90° triangle with sides 1,2,\(\sqrt 3 \)
