(A) Using a straight edge, sketch the [1̅23̅] direction within a cubic unit cell and label start and end points as well as x, y, and z axes. (B) Using a straight edge, sketch the (1̅23̅) plane within a cubic unit cell and label x, y, and z axes as well as the x, y, z axial intercepts. (C) What is the geometric relationship between the (1̅23̅) plane and the [1̅23̅] direction?
