\"\"

\

From the diagram the end points are G \"\" and H \"\"

\

The midpoint of a segment with end points \"\" is \"\"

\

\"\"      (Substitute  \"\")

\

\"\"                     (Add: \"\")

\

\"\"                  (Divide: \"\")

\

So,the midpoint of the segment \"\" is \"\"\"\"

\

The midpoint of the segment \"\" is \"\".
