Explain how to set up child routes and nested routing in Angular. Include how to configure routes and display child components.

Think about how routes are nested and where child views appear.

Describe why nested routing is useful in Angular applications and how it affects user navigation and layout.

Consider how apps with many pages keep a common header or sidebar.
