4 図のように,点A, B, C, D は円周上にあり,線分 AC と線分BDの交点をEとする。 また, ABAD である。 (1) △ABC∞△DECであることを証明せよ。 容 △ABCと△DECにおいて、 BC に対する円周角だから。 -∠BAC=∠EDC ・・・ ① AB=AD だから、 ∠ACB=∠DE ・・・ ② ① ② より, 2組の角がそれぞれ等しいから AABCO ADEC 5 図のように, △ABCの3つの頂点A,B,CはP (2) AC=6cm, BC=2cm, CD=3cmのとき, 線分AE の 長さを求めよ。 AC: DC=BC: EC より, AE =rcm とすると、 6:3=2: (6-x) 6 (6-²)=3×2 36-6x=6 -6x=-30 x=5 B 5cm
