(1) Read and prove: When both triangles are right triangles, they are obviously congruent If the two triangles are obtuse angle triangles, their congruence can be proved When these two triangles are acute triangles, they are also congruent, which can be proved as follows: Known: as shown in the figure, △ ABC, △ a1b1c1 are obtuse angle triangles, ab = A1B1, BC = b1c1, ∠ C = ∠ C1 Verification: △ BCD ≌ b1c1d1 (please complete the following certification process) It is proved that when passing through points B and B1 respectively, BD ⊥ CA is made at D, and b1d1 ⊥ c1a1 is made at D1, then ∠ BDC = ∠ b1d1c1 = 90 degree ∵BC=B1C1,∠C=∠C1 ∴△ABC≌△A1B1C1 ∴BD=B1D1. ______________________ ______________________ .
