I am a figure with 4 sides. I can be placed in the following categories: quadrilateral, parallelogram, rectangle, rhombus, and square. Explain why I fit into each category.

This shape is probably a square because only a square can be a square and a rectangle and it fits the categories of parallelogram and rhombus. It cannot be a triangle or a star because they have the wrong number of sides and don't fit the categories properly.
