A diamond is a form with four equal sides but only opposing angles that are equal. The length of each side of a square is not the only thing that is equal. For it to be a square, everything must be equal, including the distance between opposing corners. The term "diamond shape" also refers to a polygon with any number of sides but equal angles. All polygons other than a triangle and a hexagon can be described as having a diamond shape.

Squares and diamonds are two of the most basic geometric figures. It might help to think of them as the building blocks of geometry. All other figures are made up of combinations of squares and diamonds. You can combine any number of squares or diamonds into more squares or diamonds. For example, if you take a single square and double its size, you get a diamond with two equal sides and equal angles. If you keep doubling the size of the square, you will always get **a new square** with additional sides but still with equal angles. This shows that diamonds are a special type of square in which all sides are equal.

Diamonds have many interesting properties based on their overall shape and size. The first thing you should know about diamonds is that they are very hard materials found inside Earth's crust. They may be white or black depending on how much carbon has been incorporated into its structure. Diamonds are formed under high pressure and heat deep within the earth's crust.

A simpler explanation is that all angles inside a square are 90 degrees. Thus there are more unique shapes than **just squares** and diamonds.

A diamond, on the other hand, has four equal sides and straight angles at the corners. A diamond is the most symmetrical shape there is.

There are several ways that the sides of a diamond can be measured. The four straight lines that divide the diamond into two equal parts can be called the diagonals. They are equal in length and angle with respect to one another. This means that they divide the diamond into **two identical pieces**. Each diagonal passes through a corner of the diamond.

The four sides of a diamond can also be divided into **two pairs** of equal lengths. The two diagonals plus these two pairs of sides make up the total of nine equally spaced points on the diamond's surface.

These points can be used to describe the shape of the diamond. If we connect each point on one side of the diamond to its equivalent on the opposite side, we get a perfect circle. This shows that diamonds are very symmetrical!

Diamonds are the only gemstone that is completely symmetrical. This means that if you were to cut the diamond in half vertically, through the center, it would still look exactly like the original diamond.

Cutting the four equal edges of a perfect square from a natural, raw gemstone is easier than cutting a flawlessly round diamond. This is due to the fact that the form of a square-cut diamond resembles a pyramid. So, when the final pyramid is flipped on its head and inserted in the ring, the square component is visible.

Is that a diamond is a polyiamond composed of **two triangles**, but a square is a polygon composed of **four equal length sides** and four 90-degree angles; and a regular quadrilateral composed of all 90-degree angles.

A diamond is a two-dimensional flat quadrilateral having four straight sides that are closed. A diamond is also known as a rhombus because its sides are equal in length and the interior opposing angles are equal. Outside of the arithmetic classroom, diamond forms may be discovered. A diamond is a useful object for displaying items such as jewelry or trophies.

In mathematics, the term "diamond" refers to any one of **several figures** with these properties: they have exactly four sides, each side is parallel to **at least one other side**, and each angle is 90 degrees (or 180 degrees if you count both directions as separate angles). Such figures include rectangles, squares, and triangles with four right angles; more generally, any polygon with exactly four vertices can be considered a diamond. In geometry, a diamond is a figure consisting of four equidistant lines meeting at a point. The word "diamond" may also be used as an adjective to describe **such figures**: a square diamond, a rectangular diamond, etc.

The term "diamond shape" is also used to describe various figures that are not necessarily polygons. These include circles, ellipses, and hyperbolas with four focal points. Also included are parabolas whose axes of symmetry cross at right angles, such as the one shown on the left in red.
