Question

choose the correct answer. choose the 2d shape created from the cross section. rhombus rectangle square triangle

Explanation:

Step1: Analyze the shape of the cross - section

The cross - section is a quadrilateral.

Step2: Check the properties of each option

• A rhombus has all sides equal and opposite sides parallel, but we can't confirm all sides are equal from the cross - section of a rectangular prism (the fish tank).
• A square has all sides equal and all angles equal to \(90^{\circ}\). We can't be sure all sides are equal.
• A triangle has three sides. But the cross - section has four sides.
• A rectangle has opposite sides equal and all angles equal to \(90^{\circ}\). A cross - section of a rectangular prism (the fish tank) parallel to its base (assuming it's a rectangular base) will have opposite sides equal and four right angles.

Answer:

Rectangle
