Look at double bonds and dotted valence.

Double or more bonds equals a linear shape.

Also... 2 bonds = linear 3 bonds = linear if dbl or trpl bonded, otherwise bent 4 bonds = triginal poly Etc.

Lewis structures highlight the pairing of electrons to form bonds. The number of bonds and "unpaired" electrons from a Lewis dot diagram can be used in VSEPR theory (valence shell eletron pair repulsion theory) to predict the geometry.
