Describe each of the three types of symbols.

What will be an ideal response?

When you create a symbol, you can choose one of three types: graphic, movie clip, or button. Each serves a specific purpose and has a unique icon to help identify it in the Library panel. A graphic symbol is a static object usually used to create an animation spanning across frames in the Timeline. A movie clip symbol is a minimovie or animation within a Flash movie. It has its own Timeline and plays independently of the main movie's Timeline. You place it into a single frame of the main movie. A button symbol responds to users clicking or rolling over it, which activates a different part of the movie, such as playing a movie clip.
