True or false1. All parallelograms are squares.
2. All squares are parallelograms.
3. All trapezoids are scalene.
4. All squares are rhombuses.
5. All rhombuses are squares.
6. All rectangles are squares.
7. All squares are rectangles.

Final answer:

The truthfulness of these "geometric" statements varies; while all squares are parallelograms, rectangles, and rhombuses, the opposite is not true for all these shapes. The other statements are also false, as trapezoids don't need to be scalene and not all rectangles are squares.

Explanation:

The answers to these questions are dependent on the definitions of geometric shapes. Let's look at these one by one:

1. False. While all squares are parallelograms, not all parallelograms are squares. A square is a specific type of parallelogram where all sides are equal and all angles are 90 degrees.
2. True. All squares are parallelograms. This is because a square meets the definition of a parallelogram: it has two pairs of parallel sides.
3. False. A trapezoid only has one pair of parallel sides, and the other pair is not, so it doesn't necessarily have to be scalene (having sides of unequal length).
4. True. All squares are rhombuses. A square meets the definition of a rhombus as it is a parallelogram with all sides of equal length.
5. False. While all squares are rhombuses, not all rhombuses are squares. A rhombus only requires all sides to be the same length; it does not require all angles to be 90 degrees, as is the case with a square.
6. False. While all squares are rectangles, not all rectangles are squares. A rectangle is a parallelogram with all angles equal to 90 degrees. However, a square is a specific type of rectangle where all sides are also equal.
7. True. All squares are rectangles. This is because a square meets the definition of a rectangle: it is a parallelogram with four right angles.
