They are said to be perpendicular lines.
Then they are not parallel, nor skew (in 3D).
FALSE!!
one
The intersection of two lines can be any of the following:NothingA single pointAn entire line (that means the two lines are NOT distinct)
Not if they are straight lines.
A vertex? In non-euclidean geometry: A two distinct parallel lines intersect in the "Infinity zone"
Stanza
No. Two distinct points define a single line.
They are four lines that coincide pairwise in at least four distinct points.
yes
2 lines the same width apart are parallel.
Either 0 or 1 plane(s).
IT is Secant .. If I am correct .. I ain't sure about my answer =) * * * * * A transversal.
All lines are defined by two or more distinct points.
