3. Evaluate the mid point of the side of a triangle

\(\triangle ABC\) has the following mid-points \(A(\)42, 48\()\), \(B(\)24, 24\()\) and \(C(\)12, 30\()\). If \(D\) is the mid point of \(BC\), \(E\) is the mid point of \(AB\), and \(F\) is the mid point of \(AC\). Find the Mid point of the side \(BC\)
