Use the Hinge Theorem to compare the measures of AD and BD.<br><br> I need help now!!! Please!!!!

gavmur [86]

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

$AC = BC\\\angle ACD = 70 \angle BCD = 68$

So side opposite to greater angle is greater side

Therefore, length AD is greater than length BD.
