Answer:
Step-by-step explanation:
AB=BC ;given
AD=CD;given
Therefore, <DAC=<DCA; base angles of an isosceles triangle are equal
similarly, <BAC=<BCA
Therefore, BAC+DAC=BCA+DCA
Thus, we can tell that BAD =BCD
Hence proved

Answer with Step-by-step explanation:
In triangle ABC
AB=BC
Angle BAC=Angle BCA....(1)
Angle made by two equal sides are equal
In triangle ACD
AD=CD
Angle DAC=Angle DCA....(2)
Angle made by two equal sides are equal
Adding equation(1) and equation(2)
Then, we get
Hence, proved.
