Dreptunghiul

Dreptunghiul is a geometric shape. It is a quadrilateral, meaning it has four sides. All four angles in a dreptunghiul are right angles, measuring 90 degrees. A key property of a dreptunghiul is that its opposite sides are equal in length and parallel to each other. This means that if one side has a certain length, the side opposite it will have the exact same length. Similarly, opposite sides run in the same direction and never intersect.

The perimeter of a dreptunghiul is calculated by adding the lengths of all four sides. Since opposite sides are equal, a common formula for the perimeter is 2 (length + width). The area of a dreptunghiul is found by multiplying its length by its width. This gives the total space enclosed within the boundaries of the shape.

A square is a special type of dreptunghiul where all four sides are of equal length. In this case, the length and width are the same. Diagonals are lines drawn connecting opposite corners of the dreptunghiul. The diagonals of a dreptunghiul are equal in length and bisect each other, meaning they cut each other in half at their intersection point. Dreptunghiuri are fundamental shapes found in many areas of mathematics and in the real world, from architecture to everyday objects.
