Grammar books seem to split the 是……的 grammar construct into a whole bunch of cases (and here and here) using jargon like distinguishing words. I prefer to simplify, and think about this grammar construct as meaning:
X 是 Y 的
X (noun phrase) has the property Y (adjective phrase)
It's perhaps linguistically imprecise, but all we're really doing is applying some kind of adjective (described by Y) to some kind of noun (given by X).
This has the property of being true.

That car has the property of being red.
