+# Navigate to Routes
+
+Angular provides both declarative and programmatic ways to navigate between routes.
+
+## Declarative Navigation (`RouterLink`)
+
+Use the `RouterLink` directive on anchor elements.
+
+```ts
+import {RouterLink, RouterLinkActive} from '@angular/router';
+
+@Component({
+  imports: [RouterLink, RouterLinkActive],
+  template: `
+    <nav>
+      <a routerLink="/dashboard" routerLinkActive="active-link">Dashboard</a>
+      <a [routerLink]="['/user', userId]">Profile</a>
+    </nav>
+  `,
+})
+export class Nav {
+  userId = '123';
+}
+```
+
+- **Absolute Paths**: Start with `/` (e.g., `/settings`).
+- **Relative Paths**: No leading `/`. Use `../` to go up a level.
+
+## Programmatic Navigation (`Router`)
+
+Inject the `Router` service to navigate via TypeScript code.
+
+### `router.navigate()`
+
+Uses an array of commands.
+
+```ts
+private router = inject(Router);
+private route = inject(ActivatedRoute);
+
+// Standard navigation
+this.router.navigate(['/profile']);
+
+// With parameters
+this.router.navigate(['/search'], {
+  queryParams: { q: 'angular' },
+  fragment: 'results'
+});
+
+// Relative navigation
+this.router.navigate(['edit'], { relativeTo: this.route });
+```
+
+### `router.navigateByUrl()`
+
+Uses a string path. Ideal for absolute navigation or full URLs.
+
+```ts
+this.router.navigateByUrl('/products/123?view=details');
+
+// Replace current entry in history
+this.router.navigateByUrl('/login', {replaceUrl: true});
+```
+
+## URL Parameters
+
+- **Route Params**: Part of the path (e.g., `/user/123`).
+- **Query Params**: After the `?` (e.g., `/search?q=query`).
+- **Matrix Params**: Scoped to a segment (e.g., `/products;category=books`).
