New answer since accepted one no longer the case on stable angular releases, easiest way to check angular version is to do so with npm list command at project root:

npm list  @angular/core

npm list @angular/common

npm list @angular/compiler

Update since 4.0.0-rc.1

Version is added for root selector in the DOM

Since angular2 version 2.3.0-rc.0 you can get version as follows:

import { VERSION } from '@angular/core';

export class AppComponent { 
  constructor() {
    console.log(VERSION.full); // print 2.3.0-rc.0
  }
}

Or you can just open browser console and check body tag
