The terms that describe basic geometric figures that are fundamental to all other geometric figures and, as such, cannot be defined by using other geometric terms are called b. undefined terms
What are undefined terms?
Undefined terms are those words that cannot be defined using other geometric terms. They are the basic building blocks of geometry and it is from them that other concepts are formed.
Some examples of these indefined terms are points, line, space, and plane. Other complex geometric terms are defined from these words. So, they are the basic building blocks. Option B describes the statement accurately.
