Non-verbal strategies encompass the use of body language, when the individual is able to express himself using his body, through facial expressions, body postures, physical distances and gestures. Based on this, we can conclude that effective non-verbal strategies for a presentation are:
C. Standing up straight : The key to being balanced and confident in everything is posture. To be confident, keep your legs aligned with your shoulders and feet, stand up straight. So you show that you are open to the people you are talking to.
E. Moving around when possible: It is recommended that presenters of a presentation move from one end of the stage to the other when possible. So you use the whole area of the stage and get closer to the entire audience, making everyone focus on you.
D. Making eye contact: Our look communicates a multitude of information! During the presentation, it is through eye contact that we create empathy with the audience. We can convey security, firmness, attitude, and when we look into our eyes as we speak we are seen as more trustworthy and serious.
