Explore the Unit Circle

This Geogebra sketch serves as an intro to the unit circle, its symmetry, and the three foundational trigonometric ratios.
Drag the point around the unit circle to explore the various points around the circle making note of how our special right triangles 30-60-90 and the 45-45-90 triangles emerge all throughout the circle.

Where do you see the pattern of the 30-60-90 right triangle emerging?
