You can use simple vector addition. Say      a    ^    =                      O        A            →                  |                            O          A                →                |              b    ^    =                      O        B            →                  |                            O          B                →                |      Since   |      a    ^    |  =  |      b    ^    |  =  1,       c    ^    =      a    ^    +      b    ^   points along the bisector of   ∠  O  A  B
