Area of a triangle is equal to 1/2 the area of a rectangle as long as the base and height remain the same.

Thanks for the last hint it enabled me to do no. 5

I won’t be a spoiler but here is a further hint – change your mindset – not all your folds need to be “neat”.

Hope this helps..

I feel silly but I can’t even get past #3!  How do you fold the square to make a triangle that is 1/4 the area of the original square that is not congruent to the first one?  Every attempt I make no matter how I fold it ends up being the same triangle.

Ignore the folds on the paper.  They are distracting and might be inadvertently leading you to add constraints where there aren’t any.

I am sending a few hints.  Start with a fresh paper, fold it in half and ask, “Why can’t the non-congruent triangle come out of a rectangle?” Do you see it now?  I don’t think the later tasks had to be “added on” to what was done before.

As I read the task, I thought I would have extra squares of paper ready for when students asked for it or when they started to say the folds were adding a distraction.
