最终题干渲染(f_body 预览)
如图,⊙O的弦AB,CD相交于点E,且AB=CD.求证:
(1)\widehat{BC}=\widehat{AD}.
(2)EB=ED.

答案 / 解析
答案(f_answer)
(1)见解析. (2)见解析.
解析(f_ways)
\overset{(1)}{\because} AB=CD, \overset{(2)}{\therefore} \widehat{AB}=\widehat{CD} \therefore \widehat{AB}+\widehat{BD}=\widehat{CD}+\widehat{BD}, 即 \widehat{BC}=\widehat{AD}. \because BC=AD \therefore\(\angle\)B=\(\angle\)D \therefore EB=ED.
