Now that you have navigated your way through this lesson, you are able to identify and describe three undefined terms (point, line, and plane) that form the foundation of Euclidean geometry. You can also identify and describe the undefined term, set, used in geometry and set theory.

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 possibility of assuming different values). [1]

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 ".

In geometry, certain terms are considered undefined, meaning they are fundamental concepts that are not explicitly defined using other terms. They serve as the basic building blocks upon which other geometric concepts are defined. The three primary undefined terms in geometry are:

Measure of an angle. We'll write AB for the distance between two points A and B, and we'll write m\ABC for the measure of angle \ABC. We'll be careful to distinguish between an angle (which is a thing) and its measure (which is a number).
