This seems like a poor choice. In three dimensions, of course, there's
an interesting theory of equidecomposability for polyhedra, which does
not reduce to just computing volumes.

What's wrong with the obvious term "equal-area"?
As in "Any two triangles with the same base and height are equal-area
triangles." Seems precise and clear; what more would you want?
