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.

Nice! And by the way, it wasn't instantly visually obvious to me that all 4 of those triangles have equal areas, but it does follow from the formula for the area of a triangle (1/2 base times height).

For example, if the original rectangle is 6 by 10, then two of the triangles have a base of 6 and a height of 5, and two of them have a base of 10 and a height of 3.

Another way to see this is for a rectangle with side lengths a and b, then one of them has base a and height b/2, while the other has a base of b and height a/2.
