A triangle,ABC , has angle measures of 40, 40, 100 and and exactly two congruent (equal) sides. How would this triangle be classified?

Answer:
Step-by-step explanation:
Isosceles Obtuse.
It is obtuse because the largest angle is over 90.
It is Isosceles because the two base angles are equal.
If you get it wrong, it is because the question assumes that the two base angles are acute (which they are) but for this question I think you are referring to the lone angle at the top.
