which is defined using the undefined terms point and line?\no angle\no circle\no parallel lines\no ray

Brief Explanations:

An angle is formed by two rays with a common - endpoint. A ray is defined as a part of a line that has one endpoint and extends infinitely in one direction. A point is used to define the endpoint of a ray. So, an angle is defined using the undefined terms point and line. A circle is defined in terms of a set of points at a fixed distance from a center point, not directly from point and line in the same fundamental way. Parallel lines are two lines in a plane that do not intersect, and their definition is more about the relationship between two lines rather than a direct combination of point and line to form the entity.

Answer:

angle
