coextensive
Sharing identical extent
Coextensive describes things that extend equally in space, time, or scope—sharing the same boundaries or limits.
Two concepts are coextensive when they cover exactly the same territory: The city's boundaries are coextensive with the county's.
In philosophy and logic, terms are coextensive when they apply to precisely the same set of things, even if their meanings differ.
