I'm very new to angularjs. Say my app has a form. Using the inspector, I noticed that if angularjs thinks that the form is invalid, it adds an ng-invalid class to the form. Lovely.
So it seems that in order to check if the form is valid I need to pollute my code with Jquery selector?! What is the angularjs way to indicate form validity without using a form controller?

Basic Validation − First of all, the form must be checked to make sure all the mandatory fields are filled in. It would require just a loop through each field in the form and check for data. Data Format Validation − Secondly, the data that is entered must be checked for correct form and value.
$dirty means the user has changed the input value, $invalid means the address itself is invalid. Therefore the error is only shown if the user has actively changed the input value to either an empty or invalid value.
When you put <form> tag inside you ngApp, AngularJS automatically adds form controller (actually there is a directive, called form that add nessesary behaviour). The value of the name attribute will be bound in your scope; so something like <form name="yourformname">...</form> will satisfy:
A form is an instance of FormController. The form instance can optionally be published into the scope using the name attribute.
So to check form validity, you can check value of $scope.yourformname.$valid property of scope.
More information you can get at Developer's Guide section about forms.
