    Conclusion

    The reference angle is the acute angle between the terminal side of an angle and the nearest x-axis, while the angle itself is the entire angle formed by the terminal side and the initial side.

    How it works

  • Draw a line from the vertex of the angle to the x-axis.
  • Measure the angle between the terminal side of the angle and the x-axis.
