5.3A Congruent Triangles Introduction
Interact with each applet below for a few minutes to test whether you can only build ONE triangle that matches the given triangle. Note you will only be able to use three parts of the first triangle (some angles and/or sides), so do pay attention to the parts that are given to you in the first diagram.
Feel free to move the SLIDERS, BIG WHITE POINTS, or BIG RED POINTS anywhere you'd like on the screen!
