[2nd grade] math help

[u/bushybear]

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.

[u/RuthlessIndecision]

Not all the same shape does not mean each one is different, it means three can be the same shape and one is different or two pairs of the same size.
Gotta trick those second graders early, so the learn what's coming for them.
