Question

give me all the undefined words in geometry

Answer 1

Any word without a clear meaning is undefined in geometry as in any branch of methematics. There is no such thing as a mathematical term that is undefined except; they would be tagged poorly defined, and then either have it defined clearly or condemned as undefinable. I know of no such of the latter.

Answer 2

so it would be Point, Line and Plane

a point has no size or dimension
a line has no thickness
a plane has no thickness and extends forever (infinite)

Answer 3

thank you but more thn that i will give you an medal

Answer 4

In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane.

POINT (an undefined term)
In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. A point is usually named with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y).

LINE (an undefined term)
In geometry, a line has no thickness but its length extends in one dimension and goes on forever in both directions. A line is depicted to be a straight line with two arrowheads indicating that the line extends without end in two directions. A line is named by a single lowercase written letter or by two points on the line with an arrow drawn above them.

PLANE (an undefined term)
In geometry, a plane has no thickness but extends indefinitely in all directions. Planes are usually represented by a shape that looks like a tabletop or wall. Even though the diagram of a plane has edges, you must remember that the plane has no boundaries. A plane is named by a single letter (plane m) or by three non-collinear points (plane ABC).

Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the end point, and all points extending infinitely to one side of the end point.

Answer 6

nice one!!

Answer 7

:) thanks for that medal
