The concept of a ray in geometry, defined as a part of a line that starts at a point and extends infinitely in one direction, does not have a single inventor. It emerged as part of ancient Greek mathematics, particularly through the work of mathematicians like Euclid, who formalized many geometric concepts in his work "Elements." The understanding of rays has evolved over time as geometry developed, but they are fundamental to the study of lines and angles in the discipline.

Geometry was first studied in the 3rd century B.C. by Euclid.

Geometry was not really invented. There is a long history of the early discoveries in geometry. I will provide you with a reference. http://en.wikipedia.org/wiki/History_of_geometry
A ray has only one point. It goes on and on in one direction only.

It was invented to solve the purpose of naming a point.

No. He invented calculus. He did, however, study geometry.

In ordinary geometry, no. Any ray will have infinitely many points.
Not in plane Euclidean geometry.
