What is the difference between creating a complementary animation in flash and creating a traditional complementary animation?

Interstitial animations can only be created by components, if you are not a component, it will automatically generate components in the library. Also, interstitial animation is when the properties of the component change, the component itself does not change, such as transparency, coordinates, rotation, etc. Complementary shapes, on the other hand, can't happen to components, but only to shapes, and shapes that are not combined. Most of all, it changes itself, such as A becomes B, or a circle becomes a square, and so on.
