The lattice is one of the seven primitive three-dimensional lattices in which the relationship between the lattice vectors a, b, and c can be written as: a = b ≠ c

Tetragonal and hexagonal.

Step-by-step explanation:

In the seven crystal system, one divides the bravais Lattices into the 7 crystals system which are defined by the length a, b, c and the angles alpha, beta, and gamma.

Length of cubic Crystal lattice is same therefore length a=b=c for cubic

. for the Tetragonal and hexagonal.

Although in  Tetragonal α=β=γ=90° and in Hexagonal α=120°, β=γ=90°.

Monoclinic have different length like .

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
