anwar ali has a farm in the shape of a square abcd . its diagonals ac and bd intersect at o
show that triangle aob = boc=cod=doa
Answer :
We draw Anwar Ali's square shaped farm ABCD , As :
We know sides of square equal in length , So
AB = BC = CD = DA
And
We know " The diagonals of a square are the same length , And they are bisect each other ."
So ,
OA = OB = OC = OD
Now In AOB , BOC , COD And DOA
AB = BC = CD = DA ( Sides of square )
OA = OB = OC = OD ( As we know diagonals bisect each other )
So,
AOB BOC COD DOA ( By SSS rule )
We can say that
These triangle , AS :
AOB = BOC = COD = DOA ( Hence proved )
