What are common types of visual aids used in presentations?

Visual aids are essential tools in presentations that enhance understanding and retention of information. Charts, graphs, and videos are commonly used types of visual aids because they effectively illustrate complex information and ideas in a clear and engaging manner. Charts and graphs can visually represent data trends and comparisons, making numerical information easier to digest. Videos can provide dynamic content that engages the audience and showcases real-life examples, demonstrating concepts that might be difficult to convey through text alone.

While other options may include forms of communication, they do not typically serve the same purpose in presentations. For instance, slides and reports primarily consist of written content, which might not engage the audience visually. Articles and books can provide valuable information, yet they are not practical visual aids utilized during presentations. Posters and flyers can be helpful but are generally not as effective or versatile as charts, graphs, and videos in the context of conveying complex data visually and engagingly.
