如图,在同一平面内将两个全等的等腰Rt△ABC和△ADE摆放在一起,A为公共顶点,∠BAC=∠AED=90°,若△ABC固定不动,△ADE绕点A旋转,AD,AE与边BC的交点分别为F,G(点F不与点B重合,点G不与点C重合).若BG=8,AB=,CF=9,则AG=      ,AF=       .()

如图,在同一平面内将两个全等的等腰Rt△ABC和△AFG摆放在一起,A为公共顶点,∠BAC=∠AGF=90°,若△ABC固定不动,△AFG绕点A旋转,AF,AG与边BC的交点分别为D,E(点D不与点B重合,点E不与点C重合).若BD=4,DE=5,CE=3,则AD=      ,AE=       .()
