From the diagram the end points are E \"\" and F \"\"

\

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

\

\"\"      (Substitute  \"\")

\

\"\"                    (Add: \"\")

\

\"\"                        (Cancel common terms)

\

\"\"                          (Divide: \"\") \ \

\

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

\

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