2. PLACE VALUE

3. ORDERED PAIR (1,2) A pair of numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally and the second number tells how far to move vertically

6. Relations • A set of ordered pairs Example:(5,1)   (10,2)   (15,3)   (20,4)   (25,5) Functions Functions occur when x does not repeat. It does not matter if why does. Which relations are functions?

7. GREATEST COMMON FACTOR • The greatest factor that two or more numbers have in common Example:18: 1, 2, 3, 6, 9, 18 30: 1, 2, 3, 5, 6, 10, 15, 30 6 is the GCF of 18 and 30.

8. LEAST COMMON MULTIPLE (LCM)

9. MULTIPLES • multiple • The product of a given whole number and another whole number Example:

10. percent • The ratio of a number to 100; percent means "per hundred

12. measure of central tendency • A measure used to describe data; the mean, median, and mode are measures of central tendency. • Another measure of central tendency is range.

13. mean • The number found by dividing the sum of a set of numbers by the number of addends; see alsoaverageExample:74, 91, 63, 92, 85

14. mode • The numbers or items that occur most often in a set of dataExample:The mode of 1, 3, 4, 4, and 6 is 4.

15. median • The middle number or the average of the two middle numbers in an ordered set of dataExample:The median of 1, 3, 4, 6, and 7 is 4.

16. range • The difference between the greatest and least numbers in a set of dataExample:The greatest temperature is 83°F.The least temperature is 80°F.Since 83 - 80 = 3, the range is 3°F.

17. number line • A line with equally spaced tick marks named by numbers (POSITIVE AND NEGATIVE INTEGERS) • Example:

18. A number written as the product of all its primefactors

19. prime number • A whole number greater than 1 whose only factors are 1 and itself • Example 2, 3, 5, 7 • Not prime 4, 8, 12,

20. composite number • A whole number that has more than two factors • Example: 21: 1, 3, 7, 21 • Example: 4: 1, 2, 4

21. parallel lines • Lines in a plane that never intersect • A line that intersects/cuts through two parallel lines is called a transversal.

22. perpendicular lines • Two lines that intersect to form four right angles

23. congruent Having the same size and shape Example:The triangles are congruent.

24. line of symmetry A line that divides a figure into two congruent parts

25. Similar Figures Figures with the same shape but not necessarily the same size. Angles must be the same. Congruent Figures Figures must be the same size and same shape which means same size angles and lengths of sides.

27. FACE • A polygon that is a flat surface of a solid figure

28. Right Triangle • A RIGHT triangle has ONE right angle.

29. obtuse triangle A triangle that has one obtuse angleExample:

30. An ACUTE triangle has THREE acute angles. Acute Triangle

31. circumference The distance around a circleExample:

32. A DIAMETER of a circle is a chord that contains the center of the circle.  Diameter CV, diameter DT, diameter GH, diameter EU, etc..... Diameters -

33. Radius • A line segment with • one endpoint • at the center • of a circle • and the other • endpoint • on the circle

34. acute angle • An angle that has a measure less than a right angle (less than 90°) Example:

35. Straight Angle • A STRAIGHT ANGLE is one whose measure is EXACTLY 180 DEGREES.  A straight angle is made up of two opposite rays.   Another important fact is that a straight angle forms a straight line. 

36. Obtuse Angle • An OBTUSE ANGLE is one whose measure is GREATER THAN 90 AND LESS THAN 180 DEGREES.

37. Right Angle • A RIGHT ANGLE is an angle whose measure is EXACTLY 90 DEGRRES. Right angles are denoted by a small square in its interior.

38. VERTEX - • The common point for both rays is called the Vertex. 

39. Identify the Triangles • Triangles are also classified according to their length. • Scalene Triangle- no congruent sides • Isosceles Triangle- two congruent sides • Equilateral Triangle- three congruent sides

41. area The number of square units needed to cover a surface Example:The area is 9 square units.

42. Perimeter • The distance • around a figure • 2 cm + 3 cm + 3 cm • = 8 cmThe perimeter of this figure is 8 centimeters

43. VOLUME • The measure of the amount of space a solid figure occupies The volume of this figure is 24 cubic units

44. SURFACE AREA • The measure of the combined areas of each flat face of the figure. The surface area covers each face of the figure. Since there are six sides, you have to calculate areas of six sides, then add together.

45. PRISM • A solid figure that has two congruent, polygon-shaped bases, and other faces that are all rectangles

46. pyramid • A solid figure with a polygonbase and all other facestriangles that meet at a common vertex

47. Associative Property • The property that states that the way addends are grouped or factors are grouped does not change the sum or the product 12 + (5 + 9) = (12 + 5) + 9 (9 x 8) x 3 = 9 x (8 x 3)

48. Commutative Property • The property that states that when the order of addends or factors is changed, the sum or product is the same 9 + 4 = 4 + 96 x 3 = 3 x 6

49. DISTRIBUTIVE PROPERTY

50. greater than (>) A symbol used to compare two numbers, with the greater number given first Example:8 > 6 8 is greater than 6.
