Hey there!
Those are the 3 branches: the Legislative, composed of the House and Senate, is set up in Article 1 of US Constitution;
the Executive, composed of the President, Vice-President, and the Departments, is set up in Article 2;
finally, the Judicial, which is composed of the federal courts and the Supreme Court. It's set up in Article 3.
Hope this helps!
Mark as brainliest, please.
