WebApr 11, 2024 · Hint: Use the Angle Bisector theorem, An angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of triangle. Here: \[\dfrac{BD}{DC}=\dfrac{AB}{AC}\] Angle bisector is a line which bisects the internal angle exactly by half. So from above figure we can say WebJun 29, 2024 · In a ∆ABC, it is given that AD is the internal bisector of ∠A. If AB = 10cm, AC = 14cm and BC = 6cm, then CD = ?
