Direction : Among given options only for this figure perpendicular bisector theorem is used.
If DC = 4 units, Find AD.
- 8
- 16
Hint:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. T
The correct answer is:
From ADC triangle, we apply Pythagorean theorem
AB = AC = 12
DC = 4
AD = 
= 
=
