Sides of a square.

**The reasoning** A square is a special type of rectangle where **all sides are equal in length**. If you picture a square — like a window frame, a chessboard, or the face of a dice — you can count the edges: top, bottom, left, and right. That's **4 sides**. This is the definition that distinguishes a square from other shapes. It's a quadrilateral (quad = four), meaning it has four sides and four equal angles (90° each). **Why the wrong options tempt you** - **A) 2** — You might think of opposite sides (like top-bottom or left-right), but that's only counting pairs, not all sides. - **B) 3** — This is a triangle's territory. Don't mix up your shapes. - **D) 5** — That's a pentagon. Adding an extra side changes the shape entirely. **Quick takeaway** Every square has exactly **4 equal sides** — it's in the name "quad" (four). Picture it, count it, own it! 🟦
