A partition of a positive integer n is a non-increasing sequence of positive integers whose sum is n. It may be represented by a Ferrers diagram. These diagrams contain corners which are points of degree two. We define corners of types (a,b), (a+b) and (a+,b+), and also define the size of a corner. Via a generating function, we count corners of each type and corners of size $$m$$m. We also find asymptotics for the number of corners as n tends to infinity.
