    Answer:

    All statements are true, but if you try to reverse them they won’t necessarily be true.

    Let’s try:

    Square ⇒ Has 4 sides

    But if something has 4 sides it doesn’t mean it’s a square (example: rectangle)

    Angle is 80° ⇒ acute angle

    But acute angle is any angle below 90°, not just 80° so the reverse isn’t true.

    x – 17 = 4 ⇒ x = 21

    And if we reverse

    x = 21 ⇒ x – 17 = 4

    we see that it’s true for either direction.

    x = 7 ⇒ |x| = 7

    But |x| = 7 doesn’t mean that x has to be 7, x can also be -7, so the reverse isn’t true.

    x – 17 = 4, then x = 21
