The angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two side of the triangle. calculation: the ac is. ⇒ ac = ad dc. ⇒ dc = 22.4 ad. using the concept. ⇒ a d d c = a b b c. ⇒ a d 22.4 − a d = 16 9.6. ⇒ 96ad = 3584 160ad. Solution: by the angle bisector theorem, or . plugging this into and solving for ac gives . we can plug this back in to find . in triangle abc, let p be a point on bc and let . find the value of . solution: first, we notice that . thus, ap is the angle bisector of angle a, making our answer 0. part (b), 1959 imo problems problem 5. Solution: a b = 6, b c = 3. also, bd is the angle bisector. according to the angle bisector theorem, bd divides ac in the ratio proportional to the ratio of the other two sides. thus, the ratio of ad to dc is the same as the ratio of ab to bc. a b b c = a d d c. ⇒ 6 3 = a d d c. ⇒ a d: d c = 6: 3.

Solution: a b = 6, b c = 3. also, bd is the angle bisector. according to the angle bisector theorem, bd divides ac in the ratio proportional to the ratio of the other two sides. thus, the ratio of ad to dc is the same as the ratio of ab to bc. a b b c = a d d c. ⇒ 6 3 = a d d c. ⇒ a d: d c = 6: 3. So the angle bisector theorem tells us that the ratio of 3 to 2 is going to be equal to 6 to x. and then we can just solve for x. so 3 to 2 is going to be equal to 6 to x. and then once again, you could just cross multiply, or you could multiply both sides by 2 and x. that kind of gives you the same result.
