过C作CE垂直于AD延长线,CF垂直于AB,易证三角形CED全等于三角形CFB,三角形CAD全等于三角形CAF,设BF=X,则DE=X,所以可得方程21-X=9+X,解得X=6.由勾股定理可求,CE=CF=8,AC=17,即from point C to line AB is 8,and the length of AC is 17

过C作CE垂直于AD延长线，CF垂直于AB
由AC平分角DAB，易证三角形CEA全等于三角形CDB，得CF=CE
进而的三角形CED全等于三角形CFB，设BF=X，则DE=X，所以可得方程21-X=9+X，解得X=6。由勾股定理可求，CE=CF=8，AC=17，即from point C to line AB is 8，and the length of AC is 17 <...

一楼有几处三角形三个点写错了！！很明显"三角形CAD全等于三角形CAF"是错的
