Which of Sutherland's 9 propositions is considered to be the most important proposition for explaining differential association theory, the proposition which explains the differential association mechanism

abde or 1,2,4, 5 is the answer

step-by-step explanation:

19

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
