Please solve question no.22.b.(please solve don't send me any links....)
Dear Student,
Please find below the solution to the asked query:
22 ( b ) We have our diagram , As :
Here we have join FG and AC
Given : ABCD is a parallelogram So , AB | | CD , BC | | AD and AB = CD , BC = AD --- ( 1 )
And ADEF is a square so , AD = DE = EF = AF and FAD = ADE = DEF = EFA = 90 --- ( 2 )
And AGHB is a square so , AG = GH = HB = AB and AGH = GHB = HBA = BAG = 90 --- ( 3 )
And
FAG = 360 - FAD - BAG - BAD , Substitute values from equation 2 and 3 we get
FAG = 360 - 90 - 90 - BAD ,
FAG = 180 - BAD
We know ABCD is a parallelogram and we know in parallelogram adjacent angles are supplementary .
FAG = ABC --- ( 4 )
In FAG and ABC
AF = BC ( From equation 1 and equation 2 : BC = AD and AD = DE = EF = AF )
AG = AB ( From equation 3 : AG = GH = HB = AB )
And
FAG = ABC ( From equation 4 )
So,
FAG ABC ( By SAS rule )
Then,
FG = AC ( By CPCT ) ( Hence proved )
Hope this information will clear your doubts about topic.
