    they're lines that intersect I THINK!
    formula is L1 + landa L2 = 0 n then you work out the landa. they give u enough info 2 do that.

    its meh(L1)+lamda(L2)


    But generally meh is left equal to 1, i have seen questions where you have to work out both meh and lambda though.


    Theyre intersecting lines essentially, where the point of intersection of all the lines is the same, in the middle

    Ò.ó

    Please learn to spell λ lambda right...it's not hard! :D

    Concurrent lines are ones which intersect at the centre of a circle, no? Circumcentre, etc

    no concurrent lines are lines that all go through the same point. they're not part of vectors either
