Here's #C_2H_2#,

It's a bond-line drawing, so we assume that each carbon at the end has one hydrogen attached.

With that configuration, each carbon is attached to two atoms, so the hybridization of each is #"sp"#.

Hence, since there are no lone pairs present, it's safe to conclude this molecule is generally linear in geometry.
