<span>Hi! All you need to know is that cot stands for cotangent and its the reciprocal of tan i.e. cot(x) = 1/tan(x). You probably know that tan(pi/4) = 1 and that tan(3pi/4) = -1. Happily in these cases it means that cot and tan come out the same (1/1 = 1 and 1/-1 = -1).
-1 - (+1) = -2 and this divided by pi/2 = -2/(pi/2) which looks a bit untidy so multiply the top and bottom by 2 (to get rid of the 2 in pi/2) and the answer is -4/pi. HTH</span>

Answer:
AC and DF
Step-by-step explanation:
Corresponding sides as well as corresponding angles have a pair of same angles or sides that are in the same place in two different shapes that are similar.
Find attached the diagram used for solving the question
Since Δ ABC = Δ DEF
∠B corresponds to ∠E
∠A corresponds to ∠D
∠C corresponds to ∠F
As a result of the above:
Line AB corresponds to line DE
Line AC corresponds to line DF
Line BC corresponds to line EF
Therefore, if Δ ABC = Δ DEF, one of the pair of corresponding parts would be AC and DF.
