Plane, line and point. These are terms that are universally called the terms that cannot be defined.
Euclid Alexandria was known for the basic rule and terms of geometry.
an equation
no, its a postulate
The three undefined terms in geometry are:POINTLINEPLANEUNDEFINED means like it hasn't been found or an object of some sort that it doesnt know what it means
Basic geometry terms are lines, points segments and rays, so it should be "point".
A point is one of basic terms in geometry,it just specifies an exact location, we identify this point with a number or letter. example : .A .B .C .Y
It is a very basic concept which cannot be defined. Undefined terms are used to define other concepts. In Euclidean geometry, for example, point, line and plane are not defined.
Trapezoid and triangle are geometry terms. They begin with T.
are you asking for help on finding definition for geometric terms? if so go to: http://library.thinkquest.org/2647/geometry/glossary.htm#b and to wikipedia for x and j terms
Yes, you can move from basic Algebra to Geometry, but only upon recommendation from your teacher.
Do it!
