I am reading a French geometry textbook that says the following:
Pour ce qui va nous intéresser ici, deux droites qui ne se rencontrent pas (ou sont confondues) sont dites parallèles.
My English translation of this is as follows:
For what interests us, two straight lines who never meet (or are combined) are said to be parallel.
I'm wondering how the "(ou sont confondues)" should be interpreted in the context. Two lines that "combine" are not parallel, so it seems to me that this should be interpreted as saying that two straight lines who never meet, or are never combined, are said to be parallel. Is this interpretation correct?
I would appreciate it if people would please clarify this.
