Hi

2 lines are perpendicular if their direction vector are perpendicular (dot product equal to 0)

2 lines intersect if you can find one value for \(\displaystyle \lambda\) and one for \(\displaystyle \mu\) such that the coordinates are equal

l1 and l2 intersect and are perpendicular ; in the plane formed by l1 and l2 place A, P and B
