To form 90 degrees or right angles.
It can, but it need not.
Yes. A t has a perpendicular line but in order to form a right angle you need to have the lines intersect.

Perpendicular lines meet at a right angle so a right angled triangle has two lines which are perpendicular to eachother. However there are no parallel lines in a right angled triangle, or any triangles for that matter.
It need not have any.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Perpendicular lines intersect.
These lines are perpendicular: _|
Lines that aren't perpendicular
