What is an example of a check on the power of the legislative branch

An example of a check on the power of the legislative branch could be when the president decides to veto or reject a law that Congress has passed. ..However, an example of a check on the power of the executive branch could be if Congress decided to override a presidential veto. I guess another better example would be that the judicial branch has the power to declare acts of congress unconstitutional.

Hope this helps! :D
