ASA: Exercise
In the applet below, place any one (or more) of the LARGE POINTS anywhere you'd like.
You can change the size of the pink angle using the pink slider.
You can also change the size of the blue angle using the blue slider.
The "Included Side" slider controls the length of the side between the pink and blue angles.
Slide the "Slide Me" slider slowly. Carefully observe what takes place as you do.
Notice how both triangles have 2 pairs of corresponding angles congruent. In addition, the sides between these 2 pairs of corresponding congruent angles are also congruent.
Your task:
Use the transformative geometry tools to prove that the ENTIRE TRIANGLES are indeed congruent.
