there are 4 intersecting lines
a pair of intersecting lines that are perpendicular
perpendicualr lines form 90 degree angles and intersecting lines just insersect. perpendicular: _ l _ intersecting: x l
All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
The difference between intersecting and parallel lines is that, on a graph parallel lines do ont touch,cross or anything. THEY NEVER TOUCH. intersecting lines touch, or cross eachother.\
Sometimes.Perpendicular lines always intersect.Parallel lines never intersect.Therefore, intersecting lines may be perpendicular, but not always.
sometimes
Two lines in two intersecting planes can be parallel, intersecting, or skew.
Intersecting planes!
Skew Lines. :)

No, intersecting lines can intersect at any angle.
If they are straight lines, then they define a plane in which both lines lie.
they will always meet
Think you just answered your own question. A plane is a line. Two planes= two lines.
the answer would have to be skew
