Description: This page provides three applets that you manipulate in order to discover rotation, translation, and reflection. Then below are descriptions of side-angle-side, angle-side-angle, and side-side-side (triangle congruence relationships). In the first applet be sure to drag the red dot that is in the highlighted box next to the picture of the triangles that move around (NOT the red dot on the red triangle).

Courses: Geometry Congruence

Comment:Fairly basic, but nice illustration of TRANSFORMATIONS that result in congruent triangles. Synopsis of congruence postulates at the end doesn't say "postulate" and omits AAS (which could be considered a corollary).
