how do i navigate away from an angular app

so i have an angular app with custom routing set up. all `<a>` links outside any angular scope with `$route` (in my case, the only scope is the `ng-view`) navigate like normal (ie. standard location change and page reload, as if angular didn't exist) all links inside inside an angular scope with $route (ie. my `ng-view`) get routed through angular's `$routeProvider` - they are given a template and controller. my question how do i make an `<a>` link inside my `ng-view` navigate away from the angular app, to a different, static, non-angular location in the site?
