Are Shark and dolphin fins analogous or homologous?
Analogous!
What are analogous characters derived from?
Analogous characters can be traced to a distant common ancestor. Although they may differ in appearance, and somewhat in function, the analogous characters (traits) developed from an earlier functional trait. (Example : fins in fish, hands and feet in humans)
What structure supports fins?

Are the legs of a cat and the fins of a whale homologous or analogous?
Neither. Homologous structures are similar because two organisms came from a common ancestor. Analogous structures are similar because two unrelated organisms were subjected to similar environments. But the legs of a cat and the fins of a whale are not similar enough to be characterized as either homologous or analogous. The ancestors of whales were hoofed mammals, and one could argue that a hoofed mammal's leg and a cat's leg are homologous. However, after millions of years of being in the oceans, whales' fins have adapted such that they are now not at all similar to the legs of a cat.

Do reptiles have fins on the outside of their body?
Some reptiles possess characteristics which may resemble fins, but no, reptiles do not have fins. Fish have fins. An example of a fin-like structures on a reptile would be a dewlap. This is a flap on skin under some lizard's necks used primarily for territorial and mating displays. Although the fins of fish may be used for these purposes to some extent, the primary purpose of fins is moving through water. Another fin-like structure on a reptile would be a frill around the neck. The purpose of a frill is the same as a dewlap.
Are penguin flippers and bat wings homologous or analogous?
Yes they are. I disagree. Even if they ultimately come from a common ancestor, in order to classify two characteristics as homologous, they have to have some similarities. After millions of years of being in the oceans, the fins of whales have evolved such that they are not at all similar to cats' legs.
