Solve the given question using appropriate Euclid’s axiom : In the Figure, we have \(X\) and \(Y\) are the mid-points of \(AC\) and \(BC\) and \(AX = CY\). Show that \(AC = BC\).

Proof:
 
\(X\) is mid-point of \(AC\)
 
Therefore, \(2AX=\)      .....(1)
 
Also, \(Y\) is mid-point of \(BC\).
 
Therefore, \(2BY=\)   .....(2)
 
Also, AX = CY (given)         .....(3)
 
According to Euclid axiom, 'things which are double of same things are equal to one another'.
 
\(AX=CY\)     [From (3)]
 
\(AC=BC\)         [From (1) and (2)]
 
Hence, verified.
