Answer 2

Answer:

Let's begin

Step-by-step explanation:

ABC is an isosceles triangle in which AB = AC and AD is the bisector of <BAC.

In triangles ADB and ADC

AB = AC (given)

<B = <C ( as adjacent sides are equal AB = AC. then the angles of adjacent sides will also be equal)

AD is common.

<ADB = <ADC = 90 degrees , as AD is Bisector so 90 degree angle is formed.

1) Three pairs equal in triangles are AB=AC, angle B = angle C , <ADB = <ADC = 90 degrees .

2) Therefore triangles ABD and ACD are congruent as the above written parts of triangles are equal.

3) <B = <C ( as adjacent sides are equal AB = AC. then the angles of adjacent sides will also be equal)

These are the reasons, hope this helps!!!!
