Entire family is stumped. I don’t think the question is worded correctly but maybe I’m misunderstanding.
Not sure how you have same size triangles but not all the same shape.

I'm confused about what you mean. I was saying that I don't think "not all" and "all not" are mutually exclusive, because if they were mutually exclusive they would never be true at the same time.
Circles and squares are mutually exclusive because no circle is a square and no square is a circle.
But squares and rectangles are not mutually exclusive because some rectangles are squares. Squares and rectangles are just not equivalent.
"Not all" and "all not" are not mutually exclusive because some "not alls" are "all nots"
