Question 1: If they're not similar it can't be the same shape but if they have the same corresponding angles it has to be either a rectangle or a square. It can't be a rectangle so it must be a square.
Question 2: Can't be similar so it can't be the same shape. The only two shapes with side lengths proportional are the parallelogram and the rectangle. It can't be the rectangle so it must be the parallelogram.
Question 3: If it's similar it has to be the same shape so the answer must be the rectangle.
