Investigating Congruent Triangles

In the first part of the activity students investigate the nature of triangle congruency by using some dynamic sketches to manipulate triangles. Once they discover all of the congruency rules then there are some practice problems which they can do to see if they understand them. This will likely take two periods Originally this was done with the dynamic portions done via WebSketchpad.
