Answer:
Tetragonal and hexagonal.
Step-by-step explanation:
In the seven crystal system, one divides the bravais Lattices into the 7 crystals system which are defined by the length a, b, c and the angles alpha, beta, and gamma.
Length of cubic Crystal lattice is same therefore length a=b=c for cubic
. for the Tetragonal and hexagonal.
Although in Tetragonal α=β=γ=90° and in Hexagonal α=120°, β=γ=90°.
Monoclinic have different length like [tex]a\neq b\neq c[/tex].
