integer

1. integer • A number with no fractional part.

2. rational number • Any number that can be made by dividing one integer by another. The word comes from "ratio".

3. scientific notation • Scientific notation is a method of writing numbers as the product of two factors where the first factor is a number greater than or equal to 1 but less than 10 and the second factor is a power of 10.

4. perfect square • A number made by squaring a whole number.16 is a perfect square because 42 = 16

5. irrational number • A real number that cannot be written as a simple fraction - the decimal goes on forever without repeating.Example: Pi is an irrational number.

6. real numbers • The type of number we normally use, such as 1, 15.82, -0.1, 3/4, etc…Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers. They are called "Real Numbers" because they are not Imaginary Numbers.

7. Density Property • he quantity of something per unit measure, especially per unit length, area, or volume.

8. Adjacent angles • Two angles are Adjacent if they have a common side and a common vertex (corner point), and don't overlap.

9. Coefficient • A number used to multiply a variable Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient

10. Distance Formula • he distance formula is used to determine the distance, d, between two points. If the coordinates of the two points are (x1, y1) and (x2, y2), the distance equals the square root of x2 − x1 squared + y2 − y1 squared.

11. Domain • A sphere of activity, concern, or function; a field: the domain of history.

12. Hypotenuse • The side of a right triangle opposite the right angle.

13. Legs of a right Triangle • In a right triangle, the sides opposite to the acute angles are called the Legs of a Triangle.

14. Rational Number • Any number that can be made by dividing one integer by another. The word comes from "ratio".

15. Range • The area or sphere in which an activity takes place.

16. Slope • How steep a straight line is.

17. Scientific Notation • 00 is written as 7 × 102 in "Scientific Notation" • How come? • 700 = 7 × 100 • and 100 = 102(see powers of 10) • so 700 = 7 × 102 • Both 700 and 7 × 102 have the same value, just shown in different ways.

18. Prism • more ... • A solid object that has two identical ends and all flat sides.The cross section is the same all along its length.The shape of the ends give the prism a name, such as "triangular prism"

19. Scatter plot • A graph of plotted points that show the relationship between two sets of data.In this example, each dot represents one person's weight versus their height.

20. Slope intercept form • the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept

21. Absolute Value • The absolute value of a number may be thought of as its distance from zero.

22. Acute Angle • Acute angles are the smallest, being between (but not including) zero and 90° Note also that acute triangles are those where all the interior angles are acute.

23. Congruent • In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. More formally, two sets of points are called congruent if, and only if, one can be transformed into the other by an isometry, i.e., a combination of translations, rotations and reflections. This means that either object can be repositioned and reflected (but not resized) so as to coincide precisely with the other object. Two line segments are congruent if and only if they have the same length.

24. Reciprocal • Grammar Expressing mutual action or relationship. Used of some verbs and compound pronouns.

25. Vertex • In geometry, a vertex angle is the angle associated with a vertex of a polygon

26. Polygon • In geometry a polygon is a flat shape consisting of straight lines that are joined to form a closed chain or circuit.
