If two vectors OA and OB are there, then their resultant OA+OB can be found by completin the parallelogram OACB and OC=OA+OB. Also, if |OA|=|OB|, then the resultant will bisect the angle between them.
Q. If internal and external bisectors of `angleA` of `DeltaABC` meet the base BC at D and E respetively, then (D and E lie on samme side of B).

If two vectors OA and OB are there, then their resultant OA+OB can be found by completin the parallelogram OACB and OC=OA+OB. Also, if |OA|=|OB|, then the resultant will bisect the angle between them. Q.
