Answer:

Step-by-step explanation:
You can only make one because once an angle is given, the only possibility is to connect the two sides. You can't change it to an obtuse triangle with that.
Everyone else will be a congruent to the first one triangle.
SAS stands for "side, angle, side" and means that we have two congruent triangles where we know two sides and the included angle are equal.
