Algebra Vocabulary

3. To find the value of a variable that makes an equation true.
4. A relation between a set of inputs and a set of possible outputs, where each input is related to exactly one output.
5. A measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.
9. A polygon with three edges and three vertices.
11. A polygon with four edges and four vertices.
13. A figure formed by two rays with a common endpoint, known as the vertex.
14. A combination of numbers, variables, and operators (such as + and -) that represents a value.
15. The point where a line crosses an axis on a graph, typically the y-intercept or x-intercept.
17. A numerical factor that multiplies a variable in an algebraic term.
19. Figures that have the same size and shape.
21. A characteristic of a shape that can be divided into two identical parts.
22. Describing a relationship that can be graphically represented as a straight line, typically in the form of an equation.
26. A symbol (often a letter) used to represent an unknown quantity in mathematical expressions or equations.
27. A point where two or more lines meet; a corner of a shape.
29. Pertaining to a polynomial of degree two, often expressed in the form ( ax^2 + bx + c = 0 ).

1. A change in the position, size, or shape of a figure.
2. A mathematical expression that consists of variables raised to whole number powers, combined using addition, subtraction, and multiplication.
6. Lines that are always the same distance apart and never meet.
7. A mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.
8. A whole number that can be positive, negative, or zero, but not a fraction.
10. A closed figure formed by a finite number of straight line segments.
12. To divide something into two equal parts.
16. A mathematical statement that asserts the equality of two expressions, typically containing variables and constants.
18. The amount of space inside a two-dimensional shape, calculated in square units.
19. The distance around a circle, calculated as
20. The total distance around the outside of a polygon.
23. A line segment that passes through the center of a circle and has endpoints on the circumference.
24. A visual representation of data or mathematical relationships, often plotted on a coordinate plane.
25. A line segment from the center of a circle to any point on its circumference.
28. A solution to an equation, particularly where the function crosses the x-axis.
