In collections Unit Circle and Radian Defining
This example visually demonstrates the concept of unit radians to help students understand the size of radians. It involves core math concepts like radian definition, circle angle, and trigonometric functions. Constructed using GeoGebra commands such as Intersect, Point, CircleArc, Segment, and Angle. Suitable for high school students learning about radian and degree conversion.

GeoGebra Commands & Parameters

  1. Intersect(c, xAxis, 2) → B
  2. Point(yAxis) → C
  3. CircleArc(C, B, A) → RadiusLengthOnCircle
  4. Segment(C, B) → a
  5. Segment(A, C) → radius_1
  6. Angle(B, C, A) → CentralAngle
  7. Intersect(c, RadiusLengthOnCircle, 1) → D
