PLEASE MARK MY ANSWER AS THE BRAINLIEST AND FOLLOW ME DEAR

The two triangles ( triangle ABD ) and ( triangle CBD ) are congruent because:

1. Angle ( angle A ) and angle ( angle C ) are both 55°.

2. The sides ( AD ) and ( CD ) are equal.

3. The side ( BD ) is common to both triangles.

So, we can use the Angle-Side-Angle (ASA) postulate to say that ( triangle ABD ) and ( triangle CBD ) are congruent. This means the two triangles are exactly the same in size and shape.
