What is a Reflex Angle?

A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees. It is the larger angle formed when the other angle is less than 180 degrees.

How to Use the Calculator

  1. Enter the acute or obtuse angle in degrees (greater than 0 and less than 180) in the "Acute or Obtuse Angle" field.
  2. Click the "Calculate" button to compute the reflex angle.
  3. The result will be displayed in the "Reflex Angle" field.

Example

If you enter an angle of 120 degrees, the calculator will compute the reflex angle as:

Reflex Angle = 360° - 120° = 240°

Formula

The formula used by the calculator is:

Reflex Angle = 360° - Angle
