You can put this solution on YOUR website! Explain the difference, if any, between:
a) <-CD-> and <-DC->
b) -CD- and -DC-
c) CD and DC
d) CD-> and DC->
An arrow ---> over two capital letters indicates a RAY.
A line over two capital letters indicates a Line Segment.
The symbol <---> indicates a Line.
When there is NO line and/or NO arrow over capital letters, like in the case for choice (C), it also indicates line segment.
For (A) we have line CD and line DC.
For (B) and (C) we have line segments CD and DC
For (D) we have ray CD and ray DC.
