Crystals are solids with repeating geometric structures (called a unit cell)
The face centered cubic unit cell has a lattice point on each vertex of the cube and one in the middle of each face. One example of FCC crystal is table salt.

The body centered cubic has a lattice point in the middle of the cube as well as one on each vertex. One example of BCC crystal is iron.

The trigonal crystal is a like an "oblique cube" where only 2 plane angles are congruent and not equal 90 degrees. One example of trigonal system is quartz.
