Question

Which of the following are correct axial distance and axial angles for a rhombhohedral system?

• A. $a=b=c,\alpha =\beta =\gamma \ne {90}^o$
• B. $a=b\ne c,\alpha =\beta =\gamma ={90}^o$
• C. $a\ne b\ne c,\alpha =\beta =\gamma \ne {90}^o$
• D. $a\ne b\ne c,\alpha \ne \beta \ne \gamma \ne {90}^o$

Answer 1

The correct option is A $a=b=c,\alpha =\beta =\gamma \ne {90}^o$

The correct axial distance and axial angles for a rhombhohedral system are $a=b=c,\alpha =\beta =\gamma \ne {90}^o$
