drejtkëndësit

Drejtkëndëshi is the Albanian word for rectangle. A rectangle is a quadrilateral with four right angles. This means that all four interior angles of a rectangle measure 90 degrees. Opposite sides of a rectangle are equal in length and parallel.

The properties of a rectangle are crucial in geometry. If a rectangle has sides of length 'a' and 'b', its area is calculated by multiplying the lengths of its adjacent sides, so Area = a * b. The perimeter of a rectangle is the sum of the lengths of all its sides, which can be expressed as Perimeter = 2a + 2b or Perimeter = 2(a + b).

A rectangle is a special case of a parallelogram because its opposite sides are parallel. It is also a special case of an isosceles trapezoid. If all four sides of a rectangle are equal in length, it is called a square.

Rectangles are found throughout the world in many applications, from architecture and construction to everyday objects like screens, doors, and windows. Their consistent angles and predictable dimensions make them fundamental shapes in design and engineering. The symmetry of a rectangle, with its parallel sides and right angles, contributes to its stability and widespread use.
