Question

In a plane, if two lines are perpendicular to the same line. Explain the relationship between the two lines.

Answer 1

1. Only one plane can pass through three noncollinear points. 
FALSE- noncollinear points are points that do not all share the same line or plane, so it would take two planes to pass through all 3 noncollinear points. In a plane, if two lines are perpendicular to the same line then they are parrallel only if they are in the same plane and also not the identical lines 

the x y z axis are all perp to eachother 

Answer 2

False, I have at least two counterexamples. One case would be that you have the exact same line. The other case would be that the lines go off in different directions in 3-D and are therefore skew.
