A rectangle is a quadrilateral with four sides and four right angles

A rectangle is a quadrilateral with four sides and four right angles. It is a two-dimensional shape that is characterized by having opposite sides that are equal in length and parallel to each other. In other words, the opposite sides of a rectangle are congruent and the adjacent sides are perpendicular to each other.

The properties of a rectangle include:
1. All angles are right angles: The four interior angles of a rectangle are equal to 90 degrees, making all corners of the rectangle right angles.
2. Opposite sides are congruent: The two pairs of opposite sides in a rectangle are equal in length.
3. Diagonals are congruent: The diagonals of a rectangle intersect at their midpoints and are of equal length.
4. Diagonals bisect the angles: Each diagonal of a rectangle divides the interior angles into two congruent angles.

The perimeter of a rectangle is the sum of the lengths of its four sides, given by the formula: P = 2(l + w), where l represents the length and w represents the width.

The area of a rectangle is given by the formula: A = l * w, where l represents the length and w represents the width. The area of a rectangle is simply the product of its length and width.

Rectangles are commonly encountered in everyday life. Examples include the shape of most windows and doors, tables, picture frames, and book pages. The properties of rectangles make them useful in various mathematical and real-world applications.
