Angle measured in clockwise direction is positive and angle measured in anti-clockwise direction is negative
True
False
Let the angle made by the line OA with respect to positive x-axis be θ1 and the angle made by OB be θ2. Find the value of θ1+θ2(0≤|θ1|,|θ2|≤180∘). Angle measured in clockwise direction is negative and angle measured in anti-clockwise direction is positive.
If a line is making an angle of 30∘ measured in anti-clockwise direction with the horizontal, what will be the angle formed by its image in a vertical line measured in anti-clockwise direction with the horizontal?
