Things that are the same size or have the same traits are said to be equal. When it comes to people, being equal means everyone has the same rights and opportunities — and responsibilities.

When two or more things are level or balanced, they are said to be equal. This balance can refer to volume, weight, or quantity, or any other trait being compared. In a contest in which each side has the same chance of winning, the match is said to be equal. And when a person is considered at the same level with another in some respect, he or she is said to be that person's equal.
