The field of geometry and associated studies of shapes and figures reportedly originated first in the Indus River Civilization and the Babylonian Civilization around 3000 BC.
Basically, there are two types of geometric shapes: two dimensional (2D) and three dimensional (3D).
2D shapes and figures mainly consist of points and connecting lines, which form the shape.
3D figures are more complex, and consist mainly of vertices, edges, faces, etc.
It consists of nine equal sides, and sum of the angles is equal to 1260 degrees. Nine lines of symmetry are present.
It consists of ten equal sides, and sum of the angles is equal to 1440 degrees. Ten lines of symmetry are present
It consists of twelve equal sides, and sum of the angles is equal to 1800 degrees. Twelve lines of symmetry are present.
This figure is similar to an ellipse, but consists of two distinct curved lines that meet at opposite ends. In this case, two points are present at their junction.
This shape is characterized by the presence of two curved lines: one is convex and the other is concave. They meet in a similar manner as that of the lens, forming a peculiar figure.
This figure is characterized by the presence of two concentric circular structures, both of which differ in size. In most cases, the interior of the shape is not closed. This figure is also called a ring structure.
This figure has eight triangles arranged in a specific manner to form six vertices, eight faces, and twelve edges. The triangles may be either equilateral or isosceles.
They consist of twelve pentagonal faces, twenty vertices, and 30 edges. The faces are of equal-sized pentagons.
