Example 2-In figure Ray OS stands on a line POQ.Ray OR and Ray OT are angle bisectors of angle POS and angle SOQ,respectively .If angle POS=x,find angle ROT.

Example 3-In figure OP,OQ,OR and OS are four rays.Prove that angle POQ+angle QOR+angle SOR+angle POS=360 degree.

Example 5-POQ is a line.Ray OR is perpendicular to line PQ.OS is another Ray lying between rays OP an OR Prove that angle ROS=1/2(angle QOS-angle POS).

Kindly check all the solutions as early as possible.
