<PRE><B>Question 1041207</B>
.
POQ is a line . Ray OR is perpendicular to line PQ . OS is another ray lying between rays OP and OR . 
Prove that angle ROS =1/2 (ANGLE QOS - ANGLE POS  )
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


This statement is wrong.


Take angles ROS = 70 degs, QOS = 90 + 70 = 160 degs and POS = 20 degs and check.


For what reason do you post wrong problem condition to this site?


To waste our time?


Nothing to do?
