Show that the angle bisectors of a parallelogram form a rectangle.

In a triangle ABC , OB and OC are the bisector of angle angleB and angleC respectively . angleBAC = 60^@ . The angle angleBOC will be :

In the adjacent figure DeltaABC , bar(OB), bar(OC) are the angle bisectors of angleB, angleC respectively Intersect at 'O'. angleBOC =130^@ . If bar(OB)=bar(OC) , then find angleA, angleABC, angleACB .

Draw a pair of radii OA and OB such that angleBOA=120^(@) . Draw the bisector of angleBOA and draw lines perpendiculars to OA and OB at A and B . These lines meet on the bisector of angleBOA at a point which is the external point and the perpendicular lines are the required tangents . Construct and justify .
