The two diagonals are equal, the two diagonals are bisected from each other, the two groups of opposite sides are parallel, the two groups of opposite sides are equal, the four corners are all right angles, there are 2 axes of symmetry (there are 4 in the square), which is unstable (easily deformed), the square of the diagonal length of the rectangle is the sum of the squares of the two sides, and the quadrilateral obtained by connecting the midpoints of each side of the rectangle in order is a diamond.
Definition of Rectangle A rectangle is a parallelogram with a right angle at one angle. A square is a special rectangle with four sides of equal length.
Definition of length and width of a rectangleThe first opinion: according to custom, the long side of the rectangle is called long, and the short side is called wide.
The second opinion: what is in the same direction as the horizontal plane is called long, and vice versa is called wide.
The length and width of a rectangle are relative, and it cannot be absolutely said that "length is longer than width". In geometry, a rectangle (also known as a rectangle) is defined as four quadrilaterals with equal internal angles, meaning that all internal angles are right angles. From this definition, it can be concluded that the two opposite sides of a rectangle are of equal length, i.e. the rectangle is a parallelogram.
A square is a special case of a rectangle, and its four sides are of equal length. At the same time, the square is both rectangular and diamond-shaped.

A rectangle, also called a rectangle, is a flat figure that is a parallelogram with a right angle at one angle.
A rectangle is also defined as a parallelogram with all four corners at right angles. A square is a special rectangle with four sides of equal length.
Introduction
The nature of the rectangle is: two diagonals.
Equal; The two diagonals are bisected with each other; The two sets of opposite sides are parallel to each other; The two sets of opposite sides are equal; All four corners are right angles; There are 2 axes of symmetry.
There are 4 bars in the square). It is unstable (easily deformed); The square of the diagonal length of the rectangle is the sum of the squares of the two sides; The quadrilateral obtained by sequentially connecting the midpoints of each side of the rectangle is a diamond.
There is a parallelogram with right angles that is rectangular. A parallelogram with equal diagonal lines is a rectangle. A parallelogram with adjacent sides perpendicular to each other is a rectangle. There are three corners that are right angles, and the quadrilateral is rectangular.

2. The opposite sides are equal.
3. The opposite side is parallel.
4. The adjacent edge is vertical.
5. The diagonals are bisected and equal to each other.
The area of the rectangle = length and width;
1. The long side of the rectangle is called long, and the short side is called wide.
2. The one in the same direction as the horizontal plane is called long, and the opposite is called wide. The length and width of the rectangle are relative, with the long being long and the short being wide.
If s is the area of the square and a is the length of the side of the square, then: s=a.
The nature of the rectangle is: two diagonal lines are equal; The two diagonals are bisected with each other; The two sets of opposite sides are parallel to each other; The two sets of opposite sides are equal; All four corners are right angles; There are 2 axes of symmetry (4 for squares); It is unstable (easily deformed); The square of the diagonal length of the rectangle is the sum of the squares of the two sides; The quadrilateral obtained by sequentially connecting the midpoints of each side of the rectangle is a diamond.
