True or False: All rectangles are parallelograms?

1. True

2. False

3. Only some

4. Depends on definition

The correct answer is: True

The statement is true. All rectangles are indeed parallelograms because they meet the defining criteria of a parallelogram. A parallelogram is defined as a quadrilateral where both pairs of opposite sides are parallel. In a rectangle, not only are the opposite sides parallel, but all interior angles are also equal to 90 degrees. This specific angle property does not disqualify rectangles from being parallelograms; rather, it is a subset of parallelograms with additional properties. Therefore, the correct choice is true, as every rectangle can be classified under the broader category of parallelograms.
