The bisector of interior A of ∆ ABC meets BC in D. Bisector of exterior A meets BC produced in E. Prove that BD:BE = CD:CE. |
|
Answer» Step-by-step explanation: Given △ABC,AD bisects interior ∠A and AE bisects EXTERIOR ∠A meeting BC at D and BC PRODUCED at E. To PROVE: BD/BE = CD/CE Proof: In △ABC, AD bisects interior ∠A ∴ AB/AC = BD/DC (Angle bisector theorem) ..........1) Similarly in △ABC, AE bisects exterior ∠A ∴ AB/AC BE/CE ...........2) From equation (1) and (2) AB/AC = BD/DC = BE/CE = CD/CE Hence proved. |
