Using the law of syllogism, select the correct final statement: if a polygon is a square, then all 4 angles are right. if all 4 angles of a polygon are right, then it is a rectangle. question 9 options: if a polygon has 4 right angles, then it is a square. the polygon has 4 right angles. the polygon is a rectangle. if a polygon is square, then it is also a rectangle.

if a polygon is square,then it is also a rectangle is correct

Step-by-step explanation:

1)if a polygon has 4 right angles,then it is a square is wrong since in the statement a square has all its angles as right angles but it need not imply that it is a square as it could also be a rectangle

2) polygon need not have four right angles eg:rhombous with angles 60°,60°,120°,120° is also a polygon

3)every polygon need not be a rectangle as it could be square

4)if a polygon is square, then all its angles are right angles and if all its angles are right then it is rectangle.

hence option 4 is true.
