この画像の解答の話で，直前ADは、角Aの外角の二等分線であるから〜、、、 というところがどういう考え方をしたらいいのかわかりません！ 基礎が抜けてて申し訳ないです、、

要例題 79 メネラウスの定理の逆のエモ 00000 △ABCの∠Aの外角の二等分線が辺BC の延長と交わるとき,その交点を Dとする。 ∠B, ∠Cの二等分線と辺 AC, AB の交点をそれぞれ,E,F とす ると3点D,E,Fは1つの直線上にあることを示せ。 p.378 基本事項 4.基本 75 CHART & SOLUTION メネラウスの定理の逆 3点 D, E, F のうち, 点Dは△ABCの辺BC の延長上にあり,点E,Fはそれぞれ辺 AC, AB上にある。 よって, DC EA FB BD CE. AF -=1 を示すことにより, メネラウスの定理の逆から、 3点D,E,Fが1つの直線上にあることを証明できる。 解答 直線 AD は,∠A の外角の二等分線であるから中 BD AB ...... DC AC B&T CHAD CE BC また,直線BE は∠Bの二等分線であるから ② EA BA 更に, 直線 CF は ∠Cの二等分線であるから AF CA = ③エモ FB CB ① ② ③ の辺々を掛けて BD CE AF DC EA FB AB BC CASAL AC BA CB ·=1 よって,メネラウスの定理の逆により、3点D,E,Fは1つの直線上にある。 inf. 「メネラウスの定理の逆」 の証明 (p.378 基本事項 4 参照) [1] QR と辺BCの延長との交点をP'とする。 メネラウスの定理に 2点 Q,Rがそれぞれ辺 CA, AB上にあるとき (図 [1]参照), 直線 A RO BP CQ AR より =1 P'C QA RB BP CQ AR 仮定から =1 ゆえに PC QA RB BP-BC P, P' はともに辺BCの延長上にあるから, P'はPと一致し、 3点P, Q, Rは1つの直線上にある。 2点Q,Rがそれぞれ辺CA, BA の延長上にあるとき (図 [2] 参照) も同様。 PRACTICE 79° 平行四辺形ABCD内の1点Pを、各辺に平行な直 線を引き, 辺 AB, CD, BC, DA の交点を D B C [2] R ZA C B
