Why is there a 1 in 1−α here? Shouldn't it be La−α such that La−α+α=La which is the length of the altitude of (altitude is the perpendicular line dropped down from) A?
As it stands right now the altitude from A dropped down onto BC is of length 1 which does not seem like a safe assumption...

LBC(XA,YA) would be the perpendicular distance from line CB to point A. I can see how the slide is a little confusing because the (1-alpha) is not the denominator.
