Perpendicular.
No. The non-vertical angles need not be related to one another in any way.
Vertical
apex= True
Whenever two lines intersect, vertical angles refers to the angles opposite each other
Well it could be complementary or supplementary because they don't have to share a vertex yet I think you mean something like the vertical angle. You can go research vertical angles. I'll give you a link for the vertical angles. http://www.mathsisfun.com/geometry/vertical-angles.html
Yes, a pair of intersecting lines always forms a pair of vertical angles.
No. The non-vertical angles need not be related to one another in any way.

We'll get a n number of vertical angles (pairs)
When 2 straight lines intersect vertical opposite angles are equal and the 4 angles created add up to 360 degrees
Those are "vertical" angles, even if there's nothing vertical about them.
False. The angles can be formed by two skew lines intersecting a third line.
