True or false
1. 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.

The question is asking to state if those statements are true or false. First we have to mention some definitions: Parallelogram is a 4-sided flat shape with straight sides where opposite sides are parallel. And Parallelograms are: Square, rectangle and Rhombus. All Squares are Rectangles and all Rectangles are not Squares. Answers are: 1. All parallelograms are squares ( FALSE ) 2. All squares are parallelograms ( TRUE ) 3. All trapeziods are scalane ( FALSE ). 4. All squares are rhombuses ( TRUE ). 5. All rhombuses are squares ( FALSE ) 6. All rectangles are squares ( FALSE ). 7. All squares are rectangles ( TRUE ).
