A pair of lines
with same slope that will never meet.
is a quadrilateral with two pairs of parallel sides.
appear as a pair.
A ratio expressed
with a denominator of 100.
An integer that
is the square of another integer, such as 1, 4, 9. ...etc. For example,
49 is a perfect square number, since 49 = 72 .
lines intersect at a right angle are perpendicular to each other.
The slope of one line is negative reciprocal of the other.
The ratio of
the circumference of any circle to its own diameter, denoted by
. It is a transcendental number
and approximately equal to 3.14.
The place value
of a digit of a number in a counting system denotes the location
of that digit and is represented by a power of the base of that
counting system. For example, units, tens, hundreds, etc. in the
on a graph relative to a coordinate system.
Plus is an addition
A closed plane
figure bounded by three or more straight line segments that terminate
in pairs at the same number of vertices, and do not intersect other
than at their vertices.
containing two or more terms, such as .
Having a value
greater than zero.
A natural number
having no factors other than 1 and itself, such as 3,5,7,11 etc.
The result of
multiplication of two or more numbers.
of real numbers
For any real
numbers a,b, & c the following properties are valid.
i) For addiction:
a + b = b + a
Law: (a + b) + c = a + (b +c)
a + 0 = a
(opposite): a + (-a) = 0
ii) For multiplication:
Law: ab = ba
Identity: a1= 1 a = a
Inverse (reciprocal): a (1/a) = (1/a) a = 1
