Difference between Square and Rectangular

The key difference between square and rectangular shapes is that squares have equal sides and angles, while rectangles have equal opposite sides and angles.

Square Vs Rectangular

Square	Rectangular
A polygon with four equal sides	A polygon with four sides and opposite sides equal
Always a square shape	Can have various shapes and aspect ratios
All angles are equal to 90 degrees	All angles are equal to 90 degrees
Diagonals are equal in length and bisect each other at right angles	Diagonals are not equal unless it is also a square
Area = side^2	Area = length x width
Perimeter = 4 x side	Perimeter = 2 x (length + width)
Chessboard, paper, post-it notes, dice	Door, television, book, laptop, tablet

Difference between Square and Rectangular

Square

• A shape with four equal sides and four right angles.
• All angles are equal (90 degrees).
• Perimeter = 4 x side length.
• Area = side length x side length (or side length squared).

Rectangle

• A shape with four sides and four right angles, but opposite sides have equal lengths.
• Adjacent sides are equal in length and opposite sides are equal in length.
• Perimeter = 2 x (length + width).
• Area = length x width.
