I googled it to find that a method using cross products which we haven't studied yet

hmmm, thanks for the link but we haven't studied planes as yet, I'm wondering IF there is another way?

Is that more like it?

anonymous · Answer

sorry that uses the vector product which we haven't done as yet!

a related question, do 2 skew lines always have just 1 perpendicular line joining them?

anonymous · Answer

if so: maybe that is an approach to take, i.e. find the common perpendicular between the 2 skew lines?

anonymous · Answer

actually that is the correct approach!
