We have mainly nine properties of equality, namely addition property, subtraction property, multiplication property, division property, reflexive property, symmetric property, transitive property, substitution property, and square root property of equality.
Properties of equality are fundamental rules that apply to equations and express the idea that both sides of an equation are equal. If an arithmetic operation has been used on one side of the equation, then the same should be used on the other side. Properties of equality are all about balance.
Properties of equality are useful in a variety of mathematical contexts. In arithmetic, properties of equality play a key role in identifying whether or not expressions are equivalent. In algebra, properties of equality are useful for isolating and solving for an unknown variable.
The following are the properties of equality for real numbers . Some textbooks list just a few of them, others list them all. These are the logical rules which allow you to balance, manipulate, and solve equations. PROPERTIES OF EQUALITY. Reflexive Property. For all real numbers x , x = x . A number equals itself.

Properties of Equality. Algebraic Properties of Equality. Here is a quick summary of the Properties of Equality. 1) Reflexive Property of Equality. For any number [latex]a[/latex], [latex]a=a[/latex]. [latex]\Rightarrow[/latex] It states that any quantity is equal to itself. Examples: [latex]2=2[/latex] [latex]\\[/latex]
28 lis 2020 · Properties of Equality and Congruence. The basic properties of equality were introduced to you in Algebra I. Here they are again: Reflexive Property of Equality: \(AB=AB\) Symmetric Property of Equality: If \(m\angle A=m\angle B\), then \(m\angle B=m\angle A\) Transitive Property of Equality: If \(AB=CD\) and \(CD=EF\), then \(AB=EF\)
