Geometrical Shapes

Geometrical shapes are a field of mathematics that explores the qualities and measurements of flat representations. Points, lines, straight lines, planes, surfaces, and empty and three-dimensional spaces make up Geometrical Figures, which are a collection of elements or silhouettes. These figures are identified by their number of sides, size, and volume, as well as their names.

Pizza (triangle), automobile wheels (circle), umbrellas or parasols (octagon), doors (rectangle), eyeballs (ellipse), and ceilings (pyramids) are examples of figures that are part of the human world.
A geometric body is described as the length, width, height, and volume that a geometric figure occupies in space, and it might have one or two dimensions.

The prism, pyramids, Archimedes, and platonic solids are found in polygons, while solid or three-dimensional polyhedrons are called polyhedrons.

List of Geometrical Shapes names

Flat Geometrical Shapes

They are the figures that are represented by a point that corresponds to the same plane. These figures are also called dimensional. The following figures are part of this category.

  • Triangle: It is a polygon with three sides, whose points form three angles, which usually have the same length, which is 60 degrees or less.
  • Square: It has four sides and forms four 90-degree angles.
  • Circumference: It is a curve where the only line that composes it is at the same distance from the point or center.
  • Rhombus: Unlike the square, the rhombus has four sides, but they do not have angles of the same degree, even though their lines have the same length.
  • Rhomboid: Its sides are opposite, but have pairs of angles with the same length or degrees. These can be less than 45 degrees.
  • Trapezoid: It is a quadrilateral, in which only two sides are similar.
  • Rectangle: It has four sides and its lines form interior angles of 90 degrees.
  • Circle: It is limited by a circumference

Solid Geometric Shapes

  • The cube: It has six proportionate and exact square faces, that is, they have the same length. It is also called a regular hexahedron.
  • Sphere: It is formed from a semicircular surface, composed of all the points that converge in the center.
  • Cone: It is a hollow figure that has a circular base and that narrows at the top where it coincides with a point.
  • Cylinder: It is a surface composed of a curved side, a closed side, and two similar planes. Which forms its bases.
  • Pyramid: It is a polyhedron formed by any polygon. Its adjacent faces are triangles with a point as a union.
  • Prism: It has two equal and parallel polygons that form a base. Each of its parts forms parallel faces. Its shape is three-dimensional, a quality that allows it to embellish its composition by making it look from different perspectives.
  • Tetrahedron: Unlike the pyramid, this figure has four triangular sides that converge at the same point

A Geometric Figure’s Composition

  • The point: It has no dimension, length, area or volume. It does not have any angle, but it is in the center of the figures and it is the one that joins the lines to form the angles of the other figures.
  • Segment: It is a fraction or piece of a line. This dimension is shapeless just like the point.
  • Curve: It is a perennial line of one dimension, which changes its direction, depending on the figure it represents.
