4. A standard stereographic projection displays the prominent crystallographic direction or pole of an important plane lies at the center of the projection. (a) Plot a 001 standard stereographic projection with Y axis as the horizontal line (b) Identify and mark {100},{110}, and {111} poles facing you. (c) Identify and mark the symmetry system of the poles. (d) In any two random standard stereographic triangles, mark two crystallographic directions "A1" and "A2" that have similar material and physical properties. (e) The material and physical properties could be analyzed by a TEM diffraction pattern. Plot the electron diffraction pattern with the electron beam parallel to [001] [20 points]
