Question

1. which of the following statements is false?○ all squares are rhombuses.○ all rectangles are quadrilaterals○ all rhombuses are parallelograms○ all quadrilaterals are trapezoids

Explanation:

• A square is a rhombus (all sides equal, opposite sides parallel), so this is true.
• A rectangle has 4 sides, so it is a quadrilateral; this is true.
• A rhombus has two pairs of parallel sides, so it is a parallelogram; this is true.
• A trapezoid has at least one pair of parallel sides, but many quadrilaterals (like kites with no parallel sides) do not meet this, so this statement is false.

Answer:

D. All quadrilaterals are trapezoids
