WebSep 22, 2016 · Directions & sites are said to be crystallographically equivalent, because there are symmetry operators that relate them. So. learn about simpler symmetry operations (proper axes, mirror planes, centres of inversion) or advanced ones (like screw axes, glide planes, etc.) learn how to recognize them in every-day's life. WebTetragonal is a coordinate term of cubic. In crystallography terms the difference between cubic and tetragonal is that cubic is having three equal axes and all angles 90° while tetragonal is having two equal axes and one unequal, and all angles 90°.
