Given: Given: AB≅CB and DA≅DCTo prove: ∠BAD≅∠BCDList the three congruencies from the given statement or the diagram:1. AB≅CB (Given)2. DA≅DC (Given)
List Congruent Parts: List Remaining Congruent Parts:We need to identify any other congruent parts that are not explicitly given but can be inferred from the diagram or the properties of geometric figures.If AB≅CB, then by definition of a midpoint, point B is the midpoint of AC, which implies AB≅BC.
Inferred Congruent Parts: because... We can use the fact that if two sides of a triangle are congruent, then the angles opposite those sides are also congruent (Isosceles Triangle Theorem). In triangle ABD and triangle CBD: AB≅CB (Given) DA≅DC (Given) BD≅BD (Common side)
Conclusion: Therefore... By Side-Side-Side (SSS) congruence postulate, triangle ABD≅triangleCBD. (What you wanted to prove) Since the triangles are congruent, their corresponding parts are congruent as well. Therefore, ∠BAD≅∠BCD.
