Does liberal arts mathematics, the new curriculum standard of college entrance examination, examine the angle of line and surface?
Certainly, because it is the key content of elective 2, there should be a multiple-choice question and a big question. Elective course 1 2, college entrance examination accounts for 60%, at least one course, but it's not very difficult, don't worry ~ and you are a liberal arts student, lines and angles are not difficult ~ just do more.
