Hint	Answer	% Correct
(a = b ≠ c) Two angles are 90, one angles is 60 or 120*	Hexagonal	100%
(a = b = c) Forms a large cube with all 90* angles	Isometric	80%
Same in all directions	Isotropic	80%
(a = b ≠ c) All angles are 90*	Tetragonal	80%
All directions are unique	Biaxial	60%
(a ≠ b ≠ c) Two axes are 90* and one isn't	Monoclinic	60%
(a ≠ b ≠ c) All angles are 90*	Orthorhombic	60%
(a ≠ b ≠ c) No angles are 90*	Triclinic	60%
