(2)の問題が解説を読んでも難しくて意味がよくわからないです。 わかりやすく説明してくださる方いませんか🥺

右の図1のように, 正方形ABCDの紙がある。 辺BC 上に点Eを,辺CD上に点Fを,辺AD上に点Gをとる。 この紙を、右の図2のように、2点E, Gを通る直線を折 り目として折り返し、頂点Aが移った点をH, 頂点Bが 移った点を1としたとき, 線分HIは点Fを通った。また, 辺BCと線分HIの交点をJ, 辺CDと線分GHの交点をK とする。 △IJE=△CJFであるとき, 次の問いに答えな かいとうらん 図1 A D 3数 106 JE F .1 B E さい。なお、解答欄には答えのみ書きなさい。 ① 図2において,△IJE=△HKFであることを次のよ うに証明した。 図2 文中の(a)には,頂点を対応させた最もふさわ しい記号を, (b) (c)には,ふさわしい記号 を, (d) には,最もふさわしい言葉を,それぞれ A D K H 書きなさい。 ただし,複数ある (a) (c) には,それぞれ 同じ記号が入るものとする。 〔証明〕 △IJEと△HKFにおいて, 正方形を折り返した角だから,∠EIJ=∠FHK= 90° △IJE=△CJFより, 対頂角は等しいから, ② ③より ここで, 正方形の1辺だから, △IJE=△CJFより, ⑤ ⑥ ⑦より, 折り返した辺だから, <JEI= ∠JFC ZJFC=2(a) <JEI=∠(a) FH= (b) - ・IJ-JF BC= (b) IJ=CJ, JE=JF FH=BC-CJ-JE= EI= (c) (c) B E ⑧ ⑨ より EI=FH ① 4 10 より (d) | がそれぞれ等しいから, AIJE=AHKF
