Answer:Here is ur answer
Step-by-step explanation:
Soln;
AngleBEF+ angle DFE =180°[co interior angle]
According to question,
Angle GEB= angle GEF and angle GFD=angle GFE.....
Therefore , angle BEF=2GEF and angle EFD=2GFE...
now, 2GEF +2GFE+90=180°(sum of interior angle of triangle is 180°)
Hence,GEF+GFE=90°
PROVED.....
