Unit Circle with Common Angles

This example demonstrates a student-created unit circle clearly showing common angles in degrees and radians. It involves core math concepts like the unit circle, trigonometric functions, angle measurement, and coordinate geometry. The construction uses GeoGebra commands/objects such as Intersect (intersection), Point (point), Circle (circle), and Segment (segment). Suitable for high school students learning about the relationship between trigonometric functions and the unit circle, as well as for teaching coordinate geometry.
