Answer 1

Answer:

hi good night hi good night

Answer 2

Step-by-step explanation:

Firstly, I have to construct a line segment, bisecting the angle A.

So, angle 3= angle 4, (this is constructed so,)

Also, AB= BC, ( it is given),

and AD= AD ( it is common in both the triangles),

So, I can say that ∆ ABD is congruent to ∆ ACD,

Then,

angle 1= angle 2 (because these are the corresponding parts of two congruent triangles).
