Proved that ΔABD ≅ ΔACD.
To prove : ΔABD ≅ ΔACD.
Given :
ΔABC and ΔADC are two isosceles triangle.
It lies on the same base BC and vertices A and D.
From the figure,
Note : Figure is attached below.
In ΔABC,
AB = AC
Here, ΔABC is isosceles.
In ΔBDC,
BD = DC
Here, ΔBDC is isosceles.
AD = AD is common.
By applying, SSS congruent rule
ΔABC ≅ ΔACD.
Hence proved that ΔABC ≅ ΔACD.
