Question
Direction : Among given options only for this figure perpendicular bisector theorem is used.
If BD = 5 units, find AD.
Hint:
The angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle.
The correct answer is:
AB=AC
4x + 4 = 8x – 4
4x = 8
x = 2
AB = 4 
2 + 4 = 12
BD = 5 units
AD = 
= 
=
