Answer:
Explanation:
depending on the space you're considering, it would be SOMETIMES true. But usually, the 2 lines would be parralel.
What i'm saying is, that in an euclidian space, the 2 lines would be parallel. In another kind of space, the two lines could be anything...
for example: look at how longitude and lattitude are represented on a globe : they are "lines"... 2 sets of perpendicular lines...
Now look at what happens in the poles : all lines intersect! (therefore, they're not parallel, and not necessarily perpendicular either)
