executive: can check the judicial branch through pardoning orders and choosing new justices, can check the legislative branch through suggesting bills, refusing to sign bills, and executive orders (which interpret how the law is enforced) the executive branch is also checked by the legislative branch in how all cabinet members are approved by Congress and the president can be impeached by Congress as well. it is checked by the judicial branch through judicial review of executive orders.
legislative: can impeach the president, confirm justices and cabinet members, and can change the constitution. checked by presidential veto, judicial review, and well their constituents too. hope this helped.
