As I read what you've written above, none of the course materials distributed to students contain MIT-licensed code, nor anything that would make them derivatives of the code in copyright terms.
Assuming this to be correct, then as I read it, you are not obliged to reproduce the licence statement and copyright lines. The rights given to you, which include usage, are given on condition that you reproduce those texts when you reproduce verbatim copies, or substantial portions, of that software. Since you are not reproducing copies or substantial portions of the software, the obligation has no effect in your case.
If you are reproducing enough of their documentation (eg, the content at https://angular.io/) to require a copyright licence, then as the above page says "Documentation licensed under CC BY 4.0.", so you will have CC BY attribution requirements. More detail may be found about these here, but as I read them, a mere link pointer will not suffice.
