PLACE VALUE

3
ORDERED PAIR (1,2) A pair of numbers used to locate a point on apoint coordinate planecoordinate 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 pairsordered 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.factor

8
LEAST COMMON MULTIPLE (LCM)

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

10
percent The ratio of a number to 100; percent means "per hundredratio

12
measure of central tendency A measure used to describe data; the mean, median, and mode are measures of central tendency.data meanmedianmode 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 also average Example: 74, 91, 63, 92, 85 sumaverage

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

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

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

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 prime factorsproductprimefactors

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

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

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

22
perpendicular lines Two lines that intersect to form four right angleslinesintersectright 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 congruent

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 figurepolygonsolid figure

28
Right Triangle A RIGHT triangle has ONE right angle.

29
obtuse triangle A triangle that has one obtuse angle Example: triangleobtuse angle

30
Acute Triangle An ACUTE triangle has THREE acute angles.

31
circumference The distance around a circle Example: circle

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

33
Radius A line segment withline segment 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: angleright angle

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.square units

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

43
VOLUME The measure of the amount of space a solid figure occupies solid figure 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 rectanglessolid figurecongruent polygonbasesfacesrectangles

46
pyramid A solid figure with a polygon base and all other faces triangles that meet at a common vertexsolid figurepolygonbasefacestrianglesvertex

47
Associative Property The property that states that the way addends are grouped or factors are grouped does not change the sum or the productsum 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 samefactorssumproduct = 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.

51
FRACTION A number that names a part of a whole or a part of a group

52
Trends in Graphs (Positive/Negative/No Correlation)

53
Combining Like Terms

54
Solving Equations

55
