Step-by-step explanation:
The effective nonverbal strategies for a presentation include making eye contact, using natural gestures, and ensuring appropriate body language. Eye contact establishes credibility with the audience and helps to hold their attention throughout the presentation. On the other hand, standing in one place or reading from notes are not considered to be effective as they could disrupt the connection with the audience and make the presentation less engaging. Practicing in front of a mirror can help presenters control their facial expressions and gestures, making them more effective during the actual presentation. It's also essential for presenters to maintain good posture and movement, as well as to provide visual representation in presentations to reach a wider audience, considering those with visual or auditory impairments.
