SSA and SAS Interactive

Part 1: SSA
[br]Play with the interactive for a few minutes, and then try to answer the questions below.[br][br]Drag Point B to orientate the activity.
Try to create a triangle with the following dimensions. Can you do it? If so, how many triangles match the dimensions? If not, why?[br][br]Angle=[math]70^\circ[/math][br]The First Side Length (AB) = 4[br]The Second Side Length = 6
Try to create a triangle with the following dimensions. Can you do it? If so, how many triangles match the dimensions? If not, why?[br][br]Angle=[math]30^{\circ}[/math][br]The First Side Length (AB) = 10[br]The Second Side Length = 6
Try to create a triangle with the following dimensions. Can you do it? If so, how many triangles match the dimensions? If not, why?[br][br]Angle=[math]30^{\circ}[/math][br]The First Side Length (AB) = 10[br]The Second Side Length = 4
When Triangle BDE is present, what type of triangle is it?
What is the relationship between The Second Side Length lines and the circle?
Part 2: SAS
[br]Play with the interactive for a few minutes, and then try to answer the questions below.[br][br]Drag Point B to change the length of the second side AB.
Try to create a triangle with the following dimensions. Can you do it? If so, how many triangles match the dimensions? If not, why?[br][br]The First Side Length (AC) = 4[br]Angle=[math]70^\circ[/math][br]The Second Side Length = 6
Try to create a triangle with the following dimensions. Can you do it? If so, how many triangles match the dimension? If not, why?[br][br]The First Side Length (AC) = 10[br]Angle=[math]30^{\circ}[/math][br]The Second Side Length = 6

The Big Question
When working with congruent triangles, there is typically an assumption that the triangles can be created. Make a conjecture about why there is a SAS Criteria but not an SSA Criteria.
