A rectangle is a four-sided shape where all four corners are right angles (90 degrees), making it one of the most common and useful geometric forms. Rectangles matter because they appear everywhere in the real world—from buildings and windows to screens and pieces of paper—and their simple, predictable properties make them fundamental to mathematics, design, and engineering.

في الهندسة الأقليدية، المستطيل هو شكل ثنائي الأبعاد، وهو رباعي أضلاع حيث تكون زواياه الأربعة قائمة. ينبع من هذا أنّ للمستطيل زوجين من الضلعين المتقابلين والمتساويين؛ أي أنّ المستطيل هو حالة خاصة من متوازي أضلاع تكون كل زواياه قائمة.كما يعتبر المربع حالة خاصة من المستطيل تكون فيها أطوال الأضلاع الأربعة متساوية.
