in size, such as the plane represented in a CARTESIAN COORDINATE
SYSTEMgraph.
point The COORDINATESof an ordered pair on a Cartesian graph.
polygonAny closed figure in a PLANEthat has three or more LINE SEGMENTs.
ATRIANGLEis a three-sided polygon; a SQUAREand a RECTANGLE
are each four-sided polygons.
See alsoREGULAR POLYGON;SECTION IV CHARTS AND TABLES.
polyhedronA three-dimensional figure in which all of the faces of the figure
are POLYGONs.
See alsoSECTION IV CHARTS AND TABLES.
polynomialAnyEXPRESSIONthat consists of a string of MONOMIALs. For
example, 21 – x + 5xy^2 +π.Polynomials with just two TERMs are called
BINOMIALs, and polynomials with exactly three terms are called
TRINOMIALs.

positive numberA number that is greater than zero in value. A positive
number that is written as a SIGNED NUMBERis written with a “+”
sign. If a number is written without a sign, it is considered to be a
positive number.

postulateSeeAXIOM.
power Usually refers to the EXPONENT, and indicates the number of times a
particular quantity is multiplied by itself. For example, 3 to the power
of 2, written as 3^2 , indicates that 3 is multiplied by itself 2 times
(3×3); 10 to the power of 3, written as 10^3 , means that 10 is to be
multiplied by itself 3 times (10 × 10 ×10); 5 to the power of 5,
written as 5^5 , shows that 5 is to be multiplied by itself 5 times
(5× 5 × 5 × 5 ×5).

powers of 10 Numbers with a base of 10, such as 10, 100, 1,000, 10,000, and
so on, which can be written with an EXPONENTas 10, 10^2 , 10^3 , 10^4 ,
and so on.
Powers Property of EqualityEqual numbers with equal powers are equal in
value, written, if a=b,then an=bn.
prime number Any NUMBERthat is divisible only by itself and 1. For
example, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and so on.
