Answer:
There are 3 unique triangles that can be drawn with interior angles measuring 40º, 40º and 100º.
Explanation:
We should remember that according to Euclidean geometry the sum of internal angles in every triangle equals 180º and that every angle is opposed by a side. Given the values of internal triangles, the possible combinations are described below:
, 
, 
There are 3 unique triangles that can be drawn with interior angles measuring 40º, 40º and 100º.
