Points, lines & planes.
Point - a dot on a page. A point has no dimensions (length, width, height), it is usually represent by a capital letter and a dot on a page. Think of it as an infinitely small place or position on a map.
Line - an unlimited number of points along the same path. The set of points may be straight or form a curve. Normally, the term 'line' means a straight line. The 'line' has no dimensions (length, width, height) and extends unlimited in both directions. (The part of a line defined by two points, called 'endpoints', is call a line segment or 'segment'.) A 'line' is represented by a drawn line with arrowheads on each end to represent that it doesn't have endpoints. A line can be named in two ways: (1) use the capital letters representing two points on the line and place a double-headed arrow above the two letters (2) use a lowercase letter beside the line to represent it.
Plane - a flat surface that extends indefinitely in all directions. It is usually represented by a parallelogram (four sided figure) with a capital letter in one corner. Remember the plane is not limited by the parallelogram, it extends infinitely. The plane can also be represented by using three points that lie on the plane surface but not on the same line (noncollinear).
102,068,001 = 3 x 3,4022,667But definition it is not a prime number.
It is: 0.006 = 6/1000 = 3/500 in its lowest terms
6/10 in lowest terms is 3/5
2/3
It is: 0.6 or as 3/5 in its lowest terms
I am prepared to define any term in geometry. If there is some term for which you would like to have a definition, just ask.

There are typically three words in geometry that are undefined. The first is "point." A point has no dimension, length, width, or thickness. The second is "line." A line has no thickness and goes on indefinitely in both directions. The third undefined term is "plane." A plane has no thickness and has no boundaries.

The difference between defined and undefined terms is that the defined terms can be combined with each other and with undefined terms to define still more terms. These are undefined terms: 1.plane 2.point 3.line These are defined terms: 1.ray 2.union of sets 3.space 4.subset 5.set 6.proper subset 7.opposite rays 8.postulate 9.betweenness of points 10.bisector of a segment 11.midpoint of a segment 12.line segment 13.lenght of a segment 14.collinear points 15.complement of a set 16.coplanar points 17.disjoint sets 18.element 19.empy set 20.finite set 21.geometry 22.infinite set 23.intersection of sets

Plane, line and point. These are terms that are universally called the terms that cannot be defined.
Point ; Line ; Plane - Remember the Point-Line-Plane Postulate
Undifined terms are terms that don't and can't be broken down any more. Three examples: point, line, plane.
