What Are Squares and Rectangles?
Squares and rectangles are both four-sided polygons called quadrilaterals. They have straight sides and right angles (90° angles) at each corner.
Squares are special quadrilaterals where all four sides are exactly the same length. Each corner forms a perfect right angle (90 degrees).
Rectangles are quadrilaterals with opposite sides that are equal in length. All four angles are right angles, just like squares. The sides along the length are equal to each other, and the sides along the width are equal to each other.
Key Concept
All squares are rectangles, but not all rectangles are squares. A square is a special type of rectangle where all sides are equal.
Similarities Between Squares and Rectangles
Four Sides
Both shapes have four straight sides, making them quadrilaterals.
Right Angles
All four corners form perfect 90-degree angles in both shapes.
Parallel Sides
Opposite sides are parallel to each other in both shapes.
Diagonals
The diagonals are equal in length and bisect each other in both shapes.
Because they share these properties, both squares and rectangles are classified as parallelograms and quadrilaterals. They also both have two lines of symmetry (for rectangles with unequal sides) or four lines of symmetry (for squares).
Key Differences
| Property | Square | Rectangle |
|---|---|---|
| Side Lengths | All four sides equal | Opposite sides equal |
| Symmetry | Four lines of symmetry | Two lines of symmetry |
| Angles | All angles 90° | All angles 90° |
| Diagonals | Equal and perpendicular | Equal but not perpendicular |
| Special Properties | All rectangles are squares only if sides equal | Includes both squares and non-square rectangles |
Remember
A square is always a rectangle, but a rectangle is only a square when all its sides are equal.
Real-World Examples
Square Examples
Chessboard squares, floor tiles, sticky notes, waffles, picture frames (when square)
Rectangle Examples
Books, doors, smartphones, sheets of paper, television screens, windows
Square objects are less common in everyday life because most objects have different length and width. You'll find squares in games (like chessboards), decorative tiles, and some picture frames.
Rectangular objects are everywhere! Look around your room - books, windows, doors, and electronic devices are usually rectangular. This shape is practical because it allows for efficient use of space and materials.

Frequently Asked Questions
Here are answers to common questions about squares and rectangles:
Geometry Trivia
Discover interesting facts about squares, rectangles, and geometry:
Ancient Geometry
The ancient Egyptians used rectangles to survey and redistribute farmland after the annual Nile floods. Their "rope stretchers" created perfect right angles using knotted ropes in a 3-4-5 ratio.
Honeycomb Mystery
For centuries, people wondered why bees build hexagonal honeycombs instead of squares or rectangles. Mathematicians proved that hexagons use less wax to store the most honey - nature's efficient design!
World's Largest Rectangle
The largest man-made rectangle is the Kaesong Industrial Region in North Korea, measuring approximately 8 km × 4 km (5 miles × 2.5 miles). That's over 32 square kilometers!
Golden Rectangle
A special rectangle called the "Golden Rectangle" has sides in a ratio of about 1:1.618. This proportion appears in famous artworks like the Mona Lisa and in ancient Greek architecture.
