Answer:
The length AD is greater than length BD.
Step-by-step explanation:
Hinge theorem states that if two triangles have two congruent sides then the triangle with the larger angle between those sides will have longer third side
In ΔACD and ΔBCD

So side opposite to greater angle is greater side
Therefore, length AD is greater than length BD.
