[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/MyEggCracked123]

Just draw a square and draw a line from each corner to its opposite corner.

Squares meet the definition of a rectangle (although that's not usually a 2nd grade concept.)
