 ells often involve neighbour exchanges called T1 transitions. Mechanically
 \, they are irreversible rearrangements crossing an energy barrier. In thi
 s talk\, I will deploy geometric constructions of classical Euclidean geom
 etry to calculate this energy barrier for general\, isolated T1 transition
 s dominated by line tensions. I will show how regularity of cell packings\
 , tension fluctuations\, and nonlinear tensions increase this energy barri
 er\, providing the basis for coarse-grained understanding of cell neighbou
 r exchanges in continuum models of epithelia.
