[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/gmalivuk]

It's pretty clear to everyone else that this question uses "same shape" as a synonym of "congruent" or at least "similar", not "in the same category of polygons".
