Class 11 Maths Trigonometric Functions Degree Measure

Degree Measure

  • 1° = 1/360th of rotation. ( 1 complete rotation = 360 degree)
  • 1° = 60′   (1 degree =60 minutes)
  • 1′ = 60″  ( 1 minute = 60 seconds)

Lets draw 360°,180°, 270°, 410°, – 30°, 50°

 

 

Notice that Angles 410o & 50o are same,                (410o -360o ) = 50o
