#### What words are hard to define in geometry?

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”. While these words are “undefined” in the formal sense, we can still “describe” these words.

What are the basic ideas terms in geometry?

Answer: The basic geometrical concepts are dependent on three basic concepts. They are the point, line and plane. We cannot precisely define the terms. But, it refers to the mark of the position and has an accurate location.
