We prove an extension of a ham sandwich theorem for families of lines in the plane by Dujmović and Langerman. Given two setsA,Bofnlines each in the plane, we prove that it is possible to partition the plane intorclosed convex regions so that the following holds. For each regionCof the partition there is a subset oflines ofAwhose pairwise intersections are inC, and the same holds forB. In this statementonly depends onr. We also prove that the dependence onnis optimal. For a single setAofnlines, we prove that there exists a partition of the plane intorparts usingvertical lines such that each region contains the pairwise intersections of a set oflines ofA. The valueis optimal.
