Undefined terms are those terms that don’t require a formal definition. The four terms are point, line, plane, and set. A point is quite simply, a dot. Points are labeled with one capital letter.

What is undefined term in math?

In mathematics, the term undefined is often used to refer to an expression which is not assigned an interpretation or a value (such as an indeterminate form, which has the propensity of assuming different values). The term can take on several different meanings depending on the context.

What is an example of undefined?

What is an example of a defined term?

A defined term is, simply put, a term that has some sort of definition. Unlike “the” and “am”, we can put a definition to the word “she.” “She” just is defined as a term that represents us acknowledging that someone is female.

What are the three example of undefined terms?

In geometry, formal definitions are formed using other defined words or terms. There are, however, three words in geometry that are not formally defined. These words are point, line and plane, and are referred to as the “three undefined terms of geometry”.

What are the 3 undefined terms in Geometry?

In geometry, point, line, and plane are considered undefined terms because they are only explained using examples and descriptions.

Does undefined mean 0?

We can say that zero over zero equals “undefined.” And of course, last but not least, that we’re a lot of times faced with, is 1 divided by zero, which is still undefined.

How do you name undefined terms in Geometry?

In Geometry, we have several undefined terms: point, line and plane. From these three undefined terms, all other terms in Geometry can be defined. In Geometry, we define a point as a location and no size.

Which is not an undefined term in geometry *?

Gauthmathier3945. YES! We solved the question!

What are some defined terms in Geometry?

Quote:
Word example we have here a definition of calling your points and coplanar points calling your points are points that lie on the same line coplanar points are points that lie on the same plane.

How do you find undefined terms?

Quote:
Well we like to think of a point we don't want it to have actual size to it so there's really no size to it you can't measure it it has no thickness nothing. It's just a location.

Which figure represents an undefined term?

undefined term. A basic figure that is not defined in terms of other figures. The undefined terms in Geometry are point, line, and plane.

Is angle an undefined term?

Answer and Explanation: We can define an angle using the undefined term of a line. That is, we can define an angle as the corners that are created where two non-parallel… See full answer below.

Is ray a defined term?

In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray.

Which pair of undefined terms is used to define?

Which pair of undefined terms is used to define a ray? Which point is the center of the circle? The definition of an angle uses the undefined term . The definition of an angle uses the undefined term .

What is the difference between undefined terms and defined terms in your own words?

Expert Answer



An undefined term is a point, line, or plane. Examples of defined terms are angles. Undefined terms can be combined to define other terms. Defined terms can be combined with each other and with undefined terms to define more terms.

How can we define a term?

1 : a word or expression that has an exact meaning in some uses or is limited to a subject or field legal terms. 2 : a period of time fixed especially by law or custom a school term. 3 terms plural : conditions that limit the nature and scope of something (as a treaty or a will) the terms of a contract.
