Transparencies are clear sheets of plastic or film that are used to display images or text when projected onto a screen. They are often used in educational settings, such as classrooms, where teachers can use a projector to display information to students. The images or text are printed or drawn on the transparency, allowing for easy visibility and sharing of information. In addition to education, transparencies are also utilized in business presentations and meetings. They can enhance visual communication by allowing presenters to overlay information or highlight key points. This makes it easier for audiences to understand complex ideas and engage with the material being presented.
