Which correspondences are equivalent to δlmn ≅ δrst?
a) δmnl ≅ δstr and δlnm ≅ δrts

b) δmln ≅ δsrt and δnlm ≅ δstr

c) δmln ≅ δtrs and δmln ≅ δtrs

d) δnlm ≅ δrst and δlnm ≅ δtsr

A)ΔMNL ≅ ΔSTR and ΔLNM ≅ ΔRTS  

Step-by-step explanation:

From the given picture we are given that ΔLMN ≅ ΔRST

Since we know that the corresponding parts of congruent triangles are congruent.

Therefore, ∠L ≅∠R

∠M≅∠S

∠N≅∠T

Now, by arranging the above correspondences of angles at the equivalent places, the correspondences are equivalent to ΔLMN ≅ ΔRST  will be

ΔMNL ≅ ΔSTR and Δ LNM ≅ ΔRTS
