 In this paper, we present a new sufficient condition for packing circles into any right or obtuse triangle using only the circles' combined area: It is possible to pack any circle instance whose combined area does not exceed the triangle's incircle . This area condition is tight, in the sense that for any larger area , there are instances which cannot be packed.
