The statement below is followed by four options. Each option is related to the item in the statement, but only one is always true. Select the option that always holds and makes the statement true.
"A square always has ______."
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Four equal sides
The answer must hold for every square, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) Sides of 4 cm each — a square can be of any size; a square of side 2 cm is still a square.
Option (2) Two sides longer than the other two — this is never true: in a square no side is longer than another.
Option (3) Four equal sides — a square is a four-sided figure with all four sides equal and all angles 90°; a figure without equal sides is not a square, so this is always true.
Option (4) A side that is horizontal — a square drawn tilted on one corner has no horizontal side and is still a square.
