A).  No.  Has no length at all.

B).  No.  One-dimensional, yes, but both ends are known, so length is known.

C).  No.  Infinite length, yes, but two-dimensional.

D).  Yes.  One-dimensional.  One end is known, but the other end is infinite.

E).  No.  No dimensions, no length.

F).  Yes.

Answer : Ray and Line

A) Angle ---> No, one dimension are measured in one direction.  Has no length at all.

B). Segment ---> Segment is a line that has finite length. It is one dimensional but length is known.

C). Plane ----> Plane is a two-dimensional but it has infinite length.

D).  Ray -----> Ray is One-dimensional.  Ray starts at one point and it goes on infinitely. Ray has infinite length.

E).  Point -----> Point has no dimension and no length

F) Line------> Line is one dimensional . It has infinite length.
