If you go by what he said, then yes. He did defined a point which has no part. However, you should be asking is what the hell does he mean by "parts"? Turns out the Greek mathematics definition of part is equivalent to our definition of dimensions. So what he meant to say was a point is defined as something with no width or length or thickness.
a point has one line and two vertices
No, the hyperbolic parallel postulate is not one of Euclid's original five postulates. Euclid's fifth postulate, known as the parallel postulate, states that given a line and a point not on that line, there is exactly one line parallel to the original line that passes through the point. Hyperbolic geometry arises from modifying this postulate, allowing for multiple parallel lines through the given point, leading to a different set of geometric principles.

Not necessarily. In fact Euclid's axioms establish the existence of a line as being defined by two points, and the existence of a point that is not on that line.

Strictly speaking, the only geometric item that has neither length nor width is a "point", but as such, it is not considered a "figure". A geometric figure is defined as a "set of points". I suppose a point could be thought of as a set containing only one element, but that rather contradicts the intention of the definition where it refers to points in the plural.As Euclid defined it: A figure is that which is contained by any boundary or boundaries.
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.
In mathematics, a ray is defined as a part of a line that has one endpoint and extends indefinitely in one direction. It is represented by a single point and an arrow indicating the direction of the line.

The first man to define prime numbers in 300 BC. was a Greek mathematician named Euclid.
