The Checks and Balances principle goes hand in hand with the principle of Separation of Powers in the U.S. Constitution which divides the powers of the Federal Government into 3 branches being the Legislative, the Judiciary and the Executive.

For instance, Congress (Legislative) may have the power to pass laws but if the President (Executive) does not assent to it, the law will not go into effect.
Another instance is how the Supreme Court (Legislative) can declare Executive orders unconstitutional but the same Executive branch gets to nominate the members of the Supreme Court.
