Question

In a quadrilateral at ABCD AB=AD and AC bisects angle ∠A show that Δ ABC≅ΔABD.can I get the answer tomorrow if possible

Answer 1

Answer:

SAS criterion

Step-by-step explanation:

in Δ ABC and Δ ADC

AD = AB               [ Given]                                         S    

∠BAC = ∠DAC     [Given that AC bisects ∠A]         A

AC=AC                 [Common]                                     S

Hence,

            By SAS criterion Δ ABC ≅ Δ ADC
