Determine if the pair of triangles is congruent. If they are congruent, complete the congruence statement and determine which property proves the triangles congruent. If the triangles cannot be proven congruent, write *not guaranteed congruent and explain why. ​

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
