Question

2. In Fig 7.15, AB=AC and D is the mid-point of BC.
Is angle B =angle c? why?​

Answer 1

I hope this would be the expected figure

Solution:

In triangles ABD , ADC

1. AB=AC(given)

2. AD=AD (common)

3. BD=DC(Since D is the midpoint of BC)

Therefore, Triangles ABD is congruent to ADC

Therefore, Angle B = Angle c (by CPCTC)

Hence proved
