Determining Bravais Lattice from Primitive Translation Vectors

In summary, The conversation discusses the determination of bravais lattice from primitive translation vectors in a crystal with one atom basis. The given vectors are a1=3i, a2=3j, and a3=(3/2)(i+j+k). The problem also asks for the angles between these vectors and the compatible lattices. However, the angles were not given and it is suggested that they can be determined using trigonometry. The speaker does not have any idea about the compatible lattices.

hi,
i don't know how to determine bravais lattice from primitive translation vectors.The problem is as:
A crystal with one atom basis, has a set of primitive translational vectors as a1=3i, a2= 3j and a3= (3/2)(i+j+k). What is the bravais lattice.

What are the angles between these vectors? With which lattices are they compartible?

The problem did not give any angels but i think that finding angles between them is not hard as i j and k are the unit vectors using trignometry angles can be easily determined. I have no idea with which lattices they are compatible
