2.) If a parallelogram is not a square, then it is not a rectangle.
3.) All rectangles are squares.

Answer 1

it think the correct answer is 2

Answer 2

We know 3&4 are false because all rectangles are NOT squares.
#2 if a parallelogram is not a square that means it does not have four right angles and four congruent sides. It could have four right angles and not four congruent sides do it could be a rectangle.
#1 has to be false. In order to be a square it first must be a rectangle.
