The statement "All rhombuses and squares are rectangles" is false.

Here's why:

• A rectangle is defined as a quadrilateral with four right angles (90°).
• A rhombus is defined as a quadrilateral with four equal sides, but not necessarily having right angles. Most rhombuses do not have four right angles, so not all rhombuses are rectangles.
• A square is a special type of rhombus that has four equal sides and four right angles. Since a square has four right angles, all squares are rectangles.

Conclusion:

• All squares are rectangles, but not all rhombuses are rectangles. Therefore, the statement is false.

Tip: When comparing different quadrilaterals, remember that definitions are hierarchical—some shapes (like squares) belong to more than one category (e
