Answer 1

Isosceles Obtuse

Explanation:

College bridge

Answer 2

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.
