Question 1175342: Two lines, a and b, are parallel. If both of the lines are rotated 90° in the same direction and then translated to the right by the same number of units, which statement about the lines resulting from these transformations is true? Found 2 solutions by ikleyn, ewatrrr:Answer by ikleyn(52778) (Show Source):
1. If the problem is asking "which statement is true", the list of options to choose from must follow,
but it is not a case with this post.
2. I perfectly understand that the expected answer is "the lines remain parallel", but the problem
MUST say that the rotation 90 degrees is about the common center.
Otherwise, it may happen that the two parallel lines will become coincide.
