Definition (1 simple sentence):
Homologous structures are body parts in different species that have the same basic anatomy because they were inherited from a common ancestor.

Two examples:
1) Human arm, bat wing, and whale flipper — all share the same bone arrangement (humerus, radius, ulna, etc.) adapted for different functions.
2) Forelimbs of a horse and a dog — both are modified versions of the same ancestral limb used for running.

One simple sentence using the term:
The human arm and the whale flipper are homologous structures.
