6Th Period
member of the set of positive whole
numbers {1, 2, 3, . . . }, negative whole
numbers {-1, -2, -3, . . . }, and zero {0}.
number that can expressed exactly by a
ratio of two integers.
method for expressing a given quantity as a
number having significant digits necessary for
a specified degree of accuracy, multiplied by
10 to the appropriate power, as 1385.62
written as 1.386 × 10 3 .
rational number that is equal to the square
of another rational number.
number that cannot be exactly expressed
as a ratio of two integers.
rational number or the limit of a sequence
of rational numbers, as opposed to a
complex number.
 The
property that states that there always
exists another rational number between any
two given rational numbers. This means that
the set of rational numbers is dense.
 Two
angles that have the same vertex and a
side in common.
number or quantity placed (generally)
before and multiplying another quantity, as
3 in the expression 3x.
 The
distance between two points (x1, y1) and
(x2, y2) in the Cartesian coordinate system
can be given by: [(x1 - x2)2 + (y1 - y2)2]1/2.
 The
set of all possible input values for a
function or relation.
 The
side opposite the right angle in a right
 Either
of the two sides that form the right
angle in a right triangle or one of the two
congruent sides in an isosceles triangle.
number that can be written as a fraction,
or as finite or repeating decimals.
 The
difference between the maximum and
minimum values in a set of data.
 Another
name for gradient.
method for expressing a given quantity as a
number having significant digits necessary for
a specified degree of accuracy, multiplied by
10 to the appropriate power, as 1385.62
written as 1.386 × 10 3 .
space figure with two parallel polygonal
bases that are the same shape and the same
 Data
that is plotted as points on a graph to
show a possible relationship between two
sets of data.
 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.
 The
magnitude of a number regardless of its
sign. Hence, the absolute value of a number
"n" is always positive or zero, written as |n|.
When the number "n" is represented on a
number line, its absolute value is the
distance from the origin to that number.
number used to indicate the number of
times a term is used as a factor to multiply
itself. The exponent is normally placed as a
superscript after the term.
 The
result obtained when multiplying
numbers, vectors, matrices, etc.
theorem stating that in a right triangle the
area of the square on the hypotenuse is
equal to the sum of the areas of the squares
drawn on the other two legs.
triangle in which all three interior angles
are acute (less than 90°).
The likelihood or chance of a given
event happening. It is often
expressed as a fraction or decimal.
The probability that m particular
events will occur out of a total of n
possible events is m/n. A certainty
means that, out of n possible
events, all the events (n events)
will happen. Therefore, a certainty
has a probability of 1 (n/n = 1).
Similarly, an impossibility has a
probability of 0 because none will
happen out of the total n possible
events (0/n = 0).
number that can divide into another
number with no remainder.
symbol that stands for an unknown
quantity. When we make a mathematics
equation out of an ordinary statement by
using a variable(s), it makes the thinking
process mechanized and automatic, thus
making the solution process much easier.
 Find
the value of an algebraic expression by
replacing the variable(s) with the correct
numerical value(s) to perform the operation.
 The
number resulting from division.
 An
angle with a measure between 0° and
 Planar
figures or solid shapes that have the
same shape and size.
number related to another in such a way
that when these two numbers are multiplied
together their product is 1.
point at which the two rays of an angle
meet or the intersection point of two sides of
a plane figure.
closed plane figure bounded by at least
three line segments.
triangle having no two sides equal.
 The
surface included within a closed figure,
measured by the number of square units
needed to cover the surface.
 The
length of the boundary around a shape
or a figure.
 The
boundary line of a circle or the length of
such a boundary line.
 An
angle that is between 90° and 180°.
pair of angles that add up to 90°.
eight-sided polygon. A regular octagon is a
polygon that has eight equal sides and eight
equal angles.
polygon with five sides.
triangle one of whose interior angles is
four-sided plane figure whose four sides
are equal.
 The
numerator and denominator of a fraction
that have had all common factors but 1
factored out and canceled.
line about which a curve or an object may
rotate or revolve.
