You asked HOW homologous structures give evidence of evolution.
Homologous structures are features that came from the same evolutionary origin, but have differences today based on what the species needs. For instance, plants have leaves. Different species of plants may have the leaf modified into the trap of a flytrap, the tube-like pitcher of the pitcher plant, or the usual flat, broad leaf of a maple tree. These are all still leaves, and they evolved from a previous leaf. Those are homologous.
HOW do these features give evidence of evolution? Homologous features show us that a structure can be modified over time based on the environmental needs of the species. Whenever you show change over time, that's evidence of evolution. These features were alike in the past and now they are not alike.

You got that wrong...it is homologous structures that give evidence of evolution.
The classic example is the pentadactyl (five-fingered) limb, which exists in all mammals in many different forms and you can see the predecessors of in reptiles and birds.
