Given △ ABC ≌ △ def, and ∠ a = 52 & # 186;, ∠ B = 31 & # 186;, ed = 10cm, if ∠ f = ∠ C, find the degree of ∠ F and the length of ab

Given △ ABC ≌ △ def, and ∠ a = 52 & # 186;, ∠ B = 31 & # 186;, ed = 10cm, if ∠ f = ∠ C, find the degree of ∠ F and the length of ab

Because the triangle ABC ≌ triangle def, so ∠ a = D = 52 degrees, ∠ B = e = 31 degrees, so ∠ f = 180 - (52 + 31) = 97 second question: because the two triangles are congruent, so the corresponding sides are equal, so AB = de = 10cm
