This follows the general preference of the time for finite objects. The idea of . meeting is, however, infinite in nature. How then does one determine if two lines are parallel?

Diskussion der Versuchsergebnisse, We shall be interested in, among other things, the sum of the measures of the angles of a triangle, in the behavior of the critical function, in classifying types of parallel Unes, and in the determination of an absolute unit of length.

If . = {.,ℒ,.} and .′ = {.′,ℒ′,.} are metric geometries and if ϕ:.→.′; is a function, what geometric properties could we reasonably require ϕ to have?
