Text Solution



We know that when equals are subtracted from equals, the remainders are equal.


\[\begin{align} AC & = BD \\ AB + BC & = BC + CD \end{align}\]

[ Point \(B\)  lies between \(A\) and \(C\) point \(C\) lies between \(B\) and  \(D\).]

\[\begin{align} AB + BC - BC & = BC + CD - BC \\ AB & = CD\end{align}\]
