coterminous
Sharing identical limits
Coterminous describes things that share the same boundaries or limits.
Two coterminous territories end at exactly the same line: The city and county are coterminous.
The word extends to time and abstractions—coterminous terms of office begin and end together, coterminous concepts overlap completely.
Also spelled conterminous, with identical meaning.
