In the adjoining figure, if AD is the bisector of ∠A, what is AC?


Given AD is the bisector of A in ΔABC. Let AC be x cm.


We know that the angle bisector theorem states that the internal bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.





x = 4 cm


AC = 4 cm
