- 3. LINES, Coplanar straight lines that do not intersect at any point. They keep a fixed minimum distance.
- 5. A number or ratio expressed as a fraction of 100. It is often represented/ denoted by a specific sign.
- 7. A line is a number that describes both the direction and the steepness of the line. The ratio of the rise to the run, or rise divided by the run.
- 11. An equation in which two ratios are set equal to each other. A mathematical comparison between two numbers.
- 13. A line that passes through two lines in the same plane at two distinct points. It plays a role in establishing whether two or more other lines in the plane are parallel.
- 15. A motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point.
- 16. FACTOR, The factor by which a quantity multiplies itself over time. The addend by which a quantity increases or decreases over time.
- 17. Moving a shape without rotating or flipping it. The shape still looks exactly the same, just shifting the origin of the coordinate system.
- 18. A symbol and placeholder for a quantity that may change, or any mathematical object. In particular it may represent a number, a vector, a matrix, or a function.
- 19. An image or shape as it would be seen in a mirror. Flipping an object about a line without changing its size or shape.
Down
- 1. A scalar value that is a function of the entries of a square matrix. It allows characterizing some properties of the matrix and the linear map represented by the matrix.
- 2. A rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.
- 4. Set of numbers that includes whole numbers and positive and negative numbers. A number that is not a fraction.
- 6. A number that says how many times to use that number in a multiplication. It is written as a small number to the right and above the base number.
- 8. ANGLES, A pair of opposite angles formed by intersecting lines. They are always congruent.
- 9. Represents a part of a whole or, more generally, any number of equal parts. A number expressed as a quotient, in which a numerator is divided by a denominator.
- 10. The longest side of a right-angled triangle, the side opposite the right angle. The length of the _______ can be found using the Pythagorean theorem, which states that the square of the length of the _______ equals the sum of the squares of the lengths of the other two sides.
- 12. Indicates how many times one number contains another. How much of one thing there is compared to another thing.
- 13. A process that manipulates a polygon or other two-dimensional object on a plane or coordinate system. Describes how two-dimensional figures move around a plane or coordinate system.
- 14. An enumerated collection of objects in which repetitions are allowed and order matters. Can be both finite and infinite.
