- 4
- 2
- 1

Which shape is the same as a square, just turned (rotated)?
- A tilted square — same 4 sides, same 4 right angles.
- A rhombus — 4 equal sides but no right angles.
- A rectangle — right angles but unequal sides.
- A triangle — different shape entirely.
Answer: A tilted square — same 4 sides, same 4 right angles.. Properties don't change when rotated. A tilted square is still a square.
