Match the following crystal system with their axial angles.

Q. The crystal system having edge length a = b = c and axial angles, α = β = γ ≠ 90°, is

कोर लम्बाई a = b = c तथा अक्षीय कोण, α = β = γ ≠ 90° वाला क्रिस्टल निकाय है

Q. If $a,b,c$ represent cell dimensions and $\alpha ,\beta ,\gamma$ represents crystal angles then, the crystal system $a\ne b\ne c,\alpha =\gamma ={90}^{\circ },\beta \ne {90}^{\circ }$ belongs to:

Q. A line makes angles $\alpha ,\beta ,\gamma$ with the co-ordinate axes. If $\alpha +\beta ={90}^{\circ }$, then $\gamma$ =

Q. If edge lengths are a ≠ b ≠ c and axial angles are α = β = γ = 90°, then the crystal system is called

यदि कोर लम्बाईयां a ≠ b ≠ c हैं तथा अक्षीय कोण α = β = γ = 90° हैं, तो क्रिस्टल निकाय कहलाता है
