Details and assumptions
2 triangles are different if they are not congruent. 
Rotations, reflections and translations of a triangle are considered the same.

hang on... 4...?
either side a or side b is 40,
and angle a or angle b are 40
so total of 2 possible sides it could be and 2 possible angles = 4 possible triangles
answer = 4

jack1 · Answer

either the base is 40 or the sides are 40, so 2 possible permutations there
and either the top angle is 40 or the other 2 angles are each 40, so 2 possibilities there
im sticking with 4 has to be the answer
