The crystal system having the highest and the lowest symmetrises respectively, are cubic and triclinic.
Cubic

\to

Most symmetrical (a = b = c,

α = β = γ = 9 0^{\circ}

)
Triclinic

\to

Least symmetrical (

a \neq = b \neq = c, α \neq = β \neq = γ \neq = 9 0^{\circ}

)

Q. The crystal system having the highest and the lowest symmetrises respectively, are

cubic and rhombohedral

cubic and triclinic

rhombohedral and monoclinic

cubic and monoclinic

The crystal system having the highest and the lowest symmetrises respectively, are cubic and triclinic. Cubic → Most symmetrical (a = b = c, α=β=γ=90∘ ) Triclinic → Least symmetrical ( a=b=c,α=β=γ=90∘ )

The crystal system having the highest and the lowest symmetrises respectively, are cubic and triclinic.
Cubic $\to$ Most symmetrical (a = b = c, $α = β = γ = 9 0^{\circ}$ )
Triclinic $\to$ Least symmetrical ( $a \neq = b \neq = c, α \neq = β \neq = γ \neq = 9 0^{\circ}$ )
