Question

Tetragonal system has which of the following dimensions?

• A. $a=b=c,\alpha =\beta =\gamma ={90}^{\circ }$
• B. $a=b\ne c,\alpha =\beta =\gamma ={90}^{\circ }$
• C. $a\ne b\ne c,\alpha =\beta =\gamma ={90}^{\circ }$
• D. $a=b\ne c,\alpha =\beta ={90}^{\circ },\gamma ={120}^{\circ }$

Answer 1

The correct option is B

$a=b\ne c,\alpha =\beta =\gamma ={90}^{\circ }$

$a=b\ne c,\alpha =\beta =\gamma ={90}^{\circ }$
