The first image of the carousel appears in my page, however the buttons do not work and neither does the images move. I have tried using different types of bootstrap carousel but to no avail. I saw some answers which suggested to add jQuery and Bootstrap links to the top, so i tried that but didn't work either.

Bootstrap requires JQuery for this kind of actions. You either need to add jquery in your index.html or add it to angular-cli.json or angular.json (depending on your version of Angular):

Approach 1 (Recommended):

Run first this command to install both JQuery and Bootstrap:

$ npm install jquery bootstrap --save

Then add these lines to angular-cli.json or angular.json (depending on your version of Angular)

"styles": [
    "styles.css",
    "../node_modules/bootstrap/dist/css/bootstrap.min.css"
  ],
  "scripts": [
    "../node_modules/jquery/dist/jquery.min.js",
    "../node_modules/popper.js/dist/popper.min.js",
    "../node_modules/bootstrap/dist/js/bootstrap.min.js"
  ],

Approach 2 (Not recommended):

Add the needed scripts in your index.html. Be careful though as you'll download these templates each time you reload the page.
