what is directed angle
Answer :
Lets understand directed angle by fifure, let have a ray OA , As :
But we know two form a angle we have required two rays , and here we have only one rays ( OA ) , but that ray have freedom to move clockwise or anticlockwise .
Let's say our ray OA move anticlockwise and stop at some point , so now we say that ray OB ,
So,
The angle AOB formed by ray's first position ( OA ) and ray OA's second position ( OB ) ,is called " Directed angle " .
