Adwords was not in that list (madewithangular) so I simply supposed it wasn't made with angular. Neither is Analytics, or any of the tools I use from Google.
If Adwords is Angular then that's one big project on Angular (clap clap clap). However, all I ever heard was that they were planning to move to Angular2 on Dart. I wonder how that worked out.
edit: just editing to add that I´m not doubting that Google is using Angular2 in some projects, like their internal CRM (Green Tea or whatever). I simply wanted to point out that it's not used _extensively_ in their main consumer facing sites - the ones you get links to when you click on their apps dropdown menu.
