Isosceles Triangle Base Angles Theorem
Consider these Questions Before During and After your Exploration
1) In the Isosceles Triangle Applet above, how do you tell the difference between the base angles and the vertex angle of the Triangle?
2) What is the same or what changes about the base angles as you move the triangle points?
3) Using the Slider applet, what can you say about the base angles and the locations of the congruent sides?
