Trig Identities from Similar Right Triangles (I)

Applet gives students the opportunity to use similarity within right triangles to author trigonometric identities (either for the first time or as a review). The basic Pythagorean identities, quotient identities, complement identities, and other (more complex) identities can be derived from carefully observing the diagram in this applet.
