Right Triangle Trigonometry: Intro

This resource has been marked as outstanding by a GeoGebra moderator.

Applet prompts students to interactively notice that right triangles similar by AA~ Theorem have ratios of any 2 sides that remain constant. (This is obviously the result of this similarity between any two triangles with 2 pairs of congruent angles.) The definitions of the 3 main trigonometric ratios can then follow.
