26. (1) 证明:∵∠A=∠A′ AC=A′C ∠ACM=∠A′CN=900-∠MCN

(2)在Rt△ABC中

,∴∠A=900-300=600

  又∵,∴∠MCN=300

∴∠ACM=900-∠MCN=600

∴∠EMB′=∠AMC=∠A=∠MCA=600

  ∵∠B′=∠B=300

所以三角形MEB′是Rt△MEB′且∠B′=300

所以MB′=2ME

25. 证明:(1)∵CF∥BE∴EBD=FCD

又∵∠BDE=∠CDF,BD=CD

∴△BDE≌△CDF

(2)四边形BECF是平行四边形

由△BDE≌△CDF得ED=FD

∵BD=CD

∴四边形BECF是平行四边形
