Elementary shapes, often referred to as basic or fundamental shapes, are the simplest geometric figures used in mathematics and design. They serve as the foundation for more complex shapes and structures. Some common examples of elementary shapes include: 1. **Point**: A precise location in a space with no dimensions (length, width, or height). 2. **Line**: A straight path that extends infinitely in both directions and has no thickness. It is defined by two points.
The term "Circles" can refer to various concepts depending on the context: 1. **Geometric Circles**: In geometry, a circle is a simple closed shape in which all points are equidistant from a fixed point known as the center. 2. **Social Networking Platforms**: "Circles" can refer to social media features or apps that allow users to create groups (or "circles") of friends or contacts for sharing information or content with specific audiences.

The opposite faces of a cuboid are equal in area, and the shape is characterized by its length, width, and height. Key properties of a cuboid include: 1. **Faces**: It has 6 faces, all of which are rectangles.
A cylinder is a three-dimensional geometric shape characterized by its two parallel circular bases connected by a curved surface at a fixed distance from the center of the bases. Here are some key characteristics of a cylinder: 1. **Bases**: A cylinder has two circular bases that are congruent (the same size and shape) and parallel to each other. 2. **Height**: The height (h) of a cylinder is the perpendicular distance between the two bases.
A decagon is a polygon with ten sides and ten angles. In a regular decagon, all sides are equal in length and all angles are equal in measure, with each internal angle measuring 144 degrees. The sum of all internal angles in a decagon is 1,440 degrees. Decagons can be found in various fields, including architecture, design, and mathematics.
A dodecagon is a twelve-sided polygon. The term comes from the Greek words "dodeca," meaning twelve, and "gonia," meaning angle. A regular dodecagon has all sides and angles equal, while an irregular dodecagon may have sides and angles of differing lengths and measures.
An ellipse is a shape that can be defined in several ways in mathematics and geometry. Here are some key points about ellipses: 1. **Geometric Definition**: An ellipse is the set of all points in a plane where the sum of the distances from two fixed points (called foci) is constant. This characteristic gives rise to its elongated circular shape.
A hendecagon, also known as an undecagon, is a polygon with eleven sides and eleven angles. The term comes from the Greek words "hendeca," meaning eleven, and "gonia," meaning angle. In geometry, each interior angle of a regular hendecagon (where all sides and angles are equal) measures approximately 147.27 degrees, and the sum of the interior angles of a hendecagon is 1620 degrees.
A heptagon is a polygon that has seven sides and seven angles. The term "heptagon" comes from the Greek word "hepta," meaning seven. In a heptagon, the sum of the interior angles is 900 degrees, which can be calculated using the formula \((n - 2) \times 180\), where \(n\) is the number of sides. Heptagons can be regular or irregular.

In a regular hexagon, all sides are of equal length and all interior angles are equal, measuring 120 degrees each. The shape can be found in various natural and man-made structures, such as honeycomb patterns in beehives.
In geometry, a kite is a quadrilateral with two distinct pairs of adjacent sides that are equal in length. This means that one pair of adjacent sides is congruent to each other, and the other pair is also congruent to each other, but the pairs are not equal to each other. Some key properties of a kite include: 1. **Diagonals**: The diagonals of a kite intersect at right angles (90 degrees). One of the diagonals bisects the other.
A nonagon is a polygon with nine sides and nine angles. The term "nonagon" comes from the Latin word "nonus," meaning "nine," and the Greek word "gon," meaning "angle." Nonagons can be regular or irregular. - A **regular nonagon** has all nine sides of equal length and all nine interior angles equal, measuring 140 degrees each. - An **irregular nonagon** does not have equal sides or angles.

Square, now known as Block, Inc., is a financial services and mobile payment company co-founded by Jack Dorsey and Jim McKelvey in 2009. Originally, Square was best known for its point-of-sale (POS) systems and mobile payment solutions that allowed small businesses to accept card payments using a smartphone or tablet equipped with a card reader.
