View on Github →refactor(geometry/euclidean): split up file (#3926)
Split up `geometry/euclidean.lean`

into four smaller files in
`geometry/euclidean`

. There should be no changes to any of the
individual definitions, or to the set of definitions present, but
module doc strings have been expanded.
Various definitions in `geometry/euclidean/basic.lean`

are not used by
all the other files, so it would be possible to split it up further,
but that doesn't seem necessary for now, and more of those things may
be used by more other files in future. (For example,
`geometry/euclidean/circumcenter.lean`

doesn't make any use of angles
at present. But a version of the law of sines involving the
circumradius would naturally go in
`geometry/euclidean/circumcenter.lean`

, and would introduce such a
dependency.)
