Question

In a triclinic crystal system.

• A. $a \neq b \neq c$, $\alpha \neq \beta \neq \gamma$
• B. $a = b = c$, $\alpha \neq \beta \neq \gamma$
• C. $a \neq b \neq c$, $\alpha \neq \beta = \gamma$
• D. $a = b \neq c$, $\alpha = \beta = \gamma$

Answer 1

Answer: (A)

$a \neq b \neq c$, $\alpha \neq \beta \neq \gamma$

Answer 2

In a triclinic crystal a ≠ b ≠ c and α ≠ β ≠ γ ≠ 90°
