Final answer:
Both statements are false. Statement 1 should say that a square has exactly four sides, and Statement 2 should clarify that a square must have four sides, not less. The two statements are different; one misdescribes a square's properties, and the other incorrectly defines what could be a square.
Step-by-step explanation:
The question asks us to evaluate two conditional statements related to the properties of geometric shapes and determine their truth value and whether they express the same meaning.
Statement 1 is false. The correct statement is: 'If it is a square, then it has exactly four sides.' A square is defined as a quadrilateral with four equal sides and four right angles. Therefore, a square cannot have more than four sides.
Statement 2 is also false. The correct statement is: 'If it has exactly four sides, then it might be a square.' Having less than four sides does not define a square; instead, a square must have four sides. A shape with less than four sides could be a triangle, but never a square.
Furthermore, these statements do not have the same meaning; one describes an incorrect property of a square, while the other incorrectly defines what may constitute a square based on the number of sides.
