A rectangle is a quadrilateral with all of **its angles** being right angles. Because a rectangle is a parallelogram, its opposing sides are also equal. A rectangle's diagonals are equal and bisect each other. The term "parallelogram" also applies to other shapes that can be constructed by joining **two opposite vertices** of a single square; for example, a rhombus is a four-sided figure like a rectangle but not quite a square. There are several types of parallelograms, including rectangles, squares, and rhombs.

A rectangle can be a parallelogram because any shape can be divided into triangles or quadrilaterals. Quadrilaterals are simply four-sided figures such as squares and rhombs. Triangles are three-sided figures such as rectangles, trapezoids, and isosceles triangles. Any quadrilateral can be broken down into pairs of opposite sides that are equal in length, which means they can be split into two identical triangles. This includes rectangles, squares, and rhombs. Since triangles can be thought of as two opposite sides of a single square, this means that any rectangle can be transformed into a parallelogram by splitting each side into two equal parts.

In geometry, a rectangle is a two-dimensional form with four sides and four corners. Its two sides are at **right angles** to one another. As a result, a rectangle has **four 90-degree angles**. A rectangle's opposite sides are the same length and parallel. If there were no other dimensions to a rectangle, it would be all you need to draw **any object** within it.

A rectangle is said to be perpendicular or orthogonal if its four sides are equal in length. Such rectangles have equal horizontal and vertical distances between their opposite points. They are important in the construction of uniform scales and uniform meters. Rectangles are also important in architecture as they provide the simplest case for applying the Pythagorean theorem for right triangles. Right angles can be recognized by the fact that they contain three pairs of lines that intersect at right angles. These six lines define a plane area within which there are only two possible configurations for any point or line: above or below the plane.

A rectangle is parallel to itself because each side is the same length as every other side. It follows that if two rectangles are parallel, then they are identical except for their sizes. Two rectangles with unequal lengths but equal heights or widths are called hypo-rectangles. Hypo-rectangles are useful in simplifying difficult problems involving parallel rectangles.

A rectangle is a parallelogram with one right angle. A rectangle is a quadrilateral whose diagonals are equal and bisect each other. Thus, a rectangle is a quadrilateral with two pairs of **opposite angles** equal to each other.

A rectangle is a type of parallelogram in which all four angles are 90 degrees. A square is an equilateral and equiangular parallelogram. There are two ways to arrange 4 squares so that they are all equal, either by rotating **each one** 120 degrees or by reflecting each one over the middle line.

Rectangles have the following fundamental properties:

- A rectangle is a quadrilateral.
- The opposite sides are parallel and equal to each other.
- Each interior angle is equal to 90 degrees.
- The sum of all the interior angles is equal to 360 degrees.
- The diagonals bisect each other.
- Both the diagonals have the same length.

A rectangle has three characteristics: A rectangle's angles are all 90 degrees. A rectangle's opposite sides are equal and parallel. A rectangle's diagonals cut each other in half. These are the only two types of figures that can be defined as rectangles.

In mathematics, a rectangle is an axis-aligned, bounded plane figure with four right angles (90 degrees). It is one of the simplest figures used in geometry. A rectangle cannot be split into **two non-equal parts**, so it is called "a rectangle of unit length". That is why it is important to specify whether lengths are measured in units or not. The word "rectangle" comes from **the Latin word** rectus, meaning straight.

There are several types of rectangles: Cartesian, polar, and elliptical. In addition, there are also double rectangles, which are shapes with **the top left corner** removed, and upside down rectangles, which are shapes with **the bottom right corner** removed.

Rectangles are commonly found in nature and art. They are also useful in technology, where they are the basis for many designs. For example, most computer monitors and televisions are made of rectangular glass panels. Electronics companies use them because they are easy to work with in the manufacturing process.
