Question

Two lines, a and b, are parallel. If both of the lines aee rotated 90⁰ in the same direction and then translated to the right by the same number of units, which statement about the lines resulting from these transformation is true?

They will be parallel.

They will be the same line.

They will be perpendicular.

They will intersect, but they won't be perpendicular.​

Answer 1

Option A

Explanation:

The two lines if rotated by 90 degree in the same direction will remain parallel. They may become perpendicular if only one of them is rotated or will be the same line if rotated in opposite direction by same amount.

Now if these two are translated by same number of degree even then they will remain parallel. They may not remain parallel if they are translated by different angle

Hence, option A is correct
