3.  In Fig. 6.30, if AB  CD, EF 
 CD and 
 GED = 126°, find 
 AGE, 
 GEF and 
 FGE.

                
                  Given AB || CD, EFCD and 
GED = 
In the  figure\ given, 
GE is transversal. So, that AGE = 
GED =  
 [Alternate interior angles]
Also, GEF = 
GED - 
FED 
= 
 
Since AB is a straight-line 
Therefore, AGE  + 
FGE =  
So, FGE =
