Solution

In the given figure, squares ABDE and AFGC are drawn on the side AB and hypotenuse AC of the right angled triangle ABC.
In EAC,
EAC=EAB+BAC
EAC=90o+BAC ....... (i) [EAB is the angle of square ABDE]

In BAF,
BAF=CAF+BAC
BAF=90o+BAC ....... (ii) [CAF is the angle of square ACGF]
From (i) and (ii)
EAC=BAF ....... (iii)
Now, in EAC and BAF
EA=BA ..... [Sides of a square EABD]
EAC=BAF ............. From (iii)
AC=AF ......... [Sides of a square ACGF]
EACBAF ....... [By SAS rule of congruence]
Thus, the statement is true.
Hence, the answer is 1.
