    in ΔDEB and ΔDFC

     a)∠BED=∠DEF=90

     b)∠BDE=∠FDC   (VERTICALLY OPPOSITE)

          THEREFORE   ΔDFC  is similar to ΔDEB

                     THEREFORE     CD/BD=FC/BE

                    FROM 1 AS CD=BD       THEREFORE CD/BD=1

                   THEREFORE      CF/BE=1

                     SO   CF=BE
