Grace is correct because a rhombus may not have right angles.

Answer 1

Grace is correct because quadrilaterals do not have to have right angles. While rectangles have four right angles, there are many other types of quadrilaterals, such as parallelograms, trapezoids, and rhombuses, that do not necessarily have right angles. Therefore, Kathleen's statement that all quadrilaterals have right angles is not universally true.
