When two radii of a circle make an angle of 120 degree the angle between the tangents drawn at the ends of these

The angle between the two tangents is the exterior angle at point O formed between the two perpendicular lines to the radii.

So, the angle between the tangents = 180 degree - angle AOB=180degree−120 degree=60 degree

radii can be found using geometry.

If the angle between two radii of a circle is 120° , then the angle between the tangents at the ends of those radii is given by:

Formula:

• Angle between tangents= 180−Angle between radii
• Angle =180 - 120
  Angle=60

Final Answer: 60
