The adjective “Euclidean” is supposed to conjure up an attitude or outlook rather than anything more specific: the course is not a course on the Elements but a wide-ranging and (we hope) interesting introduction to a selection of topics in synthetic plane geometry, with the construction of the regular pentagon taken as our culminating problem.
