What are the Texas Holdem pair rules for determining the strength of a hand in a game of poker?

In Texas Holdem, the strength of a hand with a pair is determined by the rank of the pair itself. Higher-ranked pairs, such as a pair of aces, are stronger than lower-ranked pairs, like a pair of twos. If two players have the same pair, the strength of their hands is then determined by the ranks of their other cards.
