Question Here, a ray \(\overrightarrow{O A}\) in given figure. It starts at 0 and passes through the point A. It also passes through the point B.
(a) Can you also name it as \(\overrightarrow{O B}\)? Why?
(b) Can we write \(\overrightarrow{O B}\) as \(\overrightarrow{A O}\)? Why or why not?
(a) Yes, we can also name of ray \(\overrightarrow{O A}\) as ray \(\overrightarrow{O B}\) because initial point of both is same and going on endlessly in the same direction.
(b) No, we cannot not write \(\overrightarrow{O A}\) as \(\overrightarrow{A O}\) because initial point of a ray cannot be changed.
