AG=2AF=（约等于）AD+AE
推荐
- 如图，已知AB=AC，AD=AE．求证：BD=CE．
- 点D、E在三角形ABC的边BC上,AB=AC,AD=AE,求证,BD=CE
- 如下页图,点D,E在三角形ABC的边BC上,AB等于AC,AD等于AE.求证BD等于CE
- 已知△ABC的边BC上有两点D，E，且BD=CE，求证：AB+AC＞AD+AE．
- 点D,E在三角形ABC的边BC上,AB=AC,AD=AE,求证BD=CE
- 应当称“地球”为“水球”,因为从哪个方向看地球,海洋面积都大于陆地面积?
- Her often being late makes me angry.可以说成 Her being often late makes me angry.为什么呢
- 在锐角△ABC中，已知cosA＝45，sinB＝1213.则cosC的值是（ ） A.6365 B.−6365 C.1665 D.-1665
