Explanation:

Presentations are usually considered as demonstrations, lectures or speech from one person or group of persons to an audience to present, inform or persuade about one topic or issue. Additionally, presentations involved multiple aspects such as the features of the audience, the tools that are used to convey the information and the speaker appropriate way to convey his/ her message, in this case, there are multiple tips that help the speaker such as using body language, being confident and using eye contact, however, it is completely acceptable to glance at your notes, indeed, as a speaker it might not be possible to learn all the information and thus, having some notes and checking them for a few seconds during the presentation will help the speaker to remember all the information. Thus, "It is not acceptable to glance at your notes" is not a tip on giving a presentation, as having some notes and looking at them will help the speaker and it is not forbidden or inappropriate.
