Which of the following describes a quadrilateral that has 4 right angles?

A quadrilateral with four right angles can correctly be described as a rectangle. While a square also has four right angles, the term "rectangle" encompasses all shapes that fit this description, including squares as a specific case.

Rectangles are defined as quadrilaterals where opposite sides are equal in length, and all interior angles measure 90 degrees. This property ensures that any figure classified as a rectangle satisfies the condition of having four right angles.

In contrast, a pentagon, which has five sides, cannot be a quadrilateral and thus does not meet the criteria stated in the question. A trapezoid generally has one pair of parallel sides but does not require right angles, so it does not inherently have four right angles. Therefore, among the given choices, the rectangle is the most accurate descriptor for a quadrilateral with four right angles.
