Answer:
Components are registered to an Angular module by adding their class references to the declarations array in the module's metadata.
Step-by-step explanation:
In Angular, components are registered to a module using the declarations array in the module's metadata.
Create Components:
First, create the Angular components you want to include in your module.
Import Component Class:
In the module file (typically ending with .module.ts), import the component class you want to register.
Register Components:
In the NgModule decorator for the module, there is a declarations array.
Add the imported component class to the declarations array.
Include Module:
Make sure to include this module in the imports array of the main application module or any other module where you want to use these components.
Thus, components are registered to an Angular module by adding their class references to the declarations array in the module's metadata.
