Question

give an example of a defined term and explain what is defined

Answer 1

Defined terms can be combined with each other and with undefined terms to define still more terms.
An angle, for example, is a combination of two different rays or line segments that share a single end point.
Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them.
