How/when to use ng-click to call a route?

Suppose you are using routes:

// bootstrap
myApp.config(['$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider) {

    $routeProvider.when('/home', {
        templateUrl: 'partials/home.html',
        controller: 'HomeCtrl'
    });
    $routeProvider.when('/about', {
        templateUrl: 'partials/about.html',
        controller: 'AboutCtrl'
    });
...

And in your html, you want to navigate to the about page when a button is clicked. One way would be

<a href="#/about">

… but it seems ng-click would be useful here too.

1. Is that assumption correct? That ng-click be used instead of anchor?
2. If so, how would that work? IE:

<div ng-click="/about">
