Angular is (loosely) a superset of what Svelte provides: it's a templating engine, it has a built-in forms library, built-in routing, dependency injection, baked in i18n support, and better XSS sanitization than other frameworks. Angular's templating engine is fairly complex too; it, for example, has a concept of "pipes", so you can write something like this: "<div>{{data | json}}</div>" which will take a JS object, data, and pipe it through a function that returns a stringified version of it, which is what is used in your template. (Compared to other frameworks, this might seem obsolete since JSX is syntactic sugar for JS: in React, you'd just write: "<div>{{JSON.stringify(data)}}</div>").

It's commonly used with Angular CLI to have simple commands like "ng serve" and "ng build" to bundle your application. It also heavy handedly imposes constraints on the architecture of your application-- to some, that's a benefit. All Angular apps kind of look the same.
