Question

Given: O is the midpoint of line MN OM=OW Prove: OW=ON

Answer 1

Given:
O is the midpoint of line MN
OM = OW

To prove:  OW = ON

Statement                                 Reason
1> OM = OW  -------------------------> Given
2> OM = ON ---------------------------> O is the midpoint of line MN
                                                           i.e Point O bisects line MN
3> OM = OW --------------------------> From statement <1>
4> ON = OW  -------------------------> OM = ON (Statement <2>)
     OW = ON
              
                                                                    proved!!
