Explanation For No.1
A line segment has two endpoints. A line has no end point. A line-segment has a definite length.
So the Answer is Ray because ray is a line that only has one defined endpoint and one side that extends endlessly away from the endpoint. A ray is named by its endpoint and by another point on the line. The angle that is formed by two rays that have the same endpoint is called the vertex.
Hope it helps
