Equality is a fundamental concept in mathematics that expresses the idea that two quantities or expressions are equal to each other. When working with equations or mathematical statements, equality key words are commonly used to indicate that two expressions are equal. These key words allow us to translate word problems or real-life situations into mathematical equations.

Here are some common equality key words and their meanings:

1. Equals or is equal to: These key words signify that the quantities on both sides of the equation are identical. For example, if x = 5, it means that the value of x is equal to 5.

2. Is the same as: This key phrase also indicates that the quantities on both sides of the equation are identical. For instance, if y is the same as 3, it can be represented as y = 3.

3. Is equivalent to: This key phrase implies that two expressions have the same value, even though they may look different. For example, 2 + 3 is equivalent to 5.

4. Identical to: This key phrase suggests that two expressions are exactly the same and have the same value. For instance, if a = b, it means that a is identical to b, and they are equal.

5. Congruent to: This key phrase is often used when working with geometric figures, such as triangles or circles. It indicates that two figures have the same shape and size.

These equality key words help us express mathematical relationships and solve equations. When encountering word problems, it is crucial to identify these key words to set up accurate equations and solve for unknowns.
