Where does the word "geo" come from?
Geometry. The word ‘ Geometry ‘ is derived from the Greek words ‘Geo’ (meaning ‘ earth ‘) and ‘Metron’ (meaning ‘measurement’). Over the years the subject has become a part of Mathematics with the inclusion of shapes, areas and perimeters.
What is a shape in geometry?
In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes. Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as square, circle, etc. Irregular shapes are asymmetrical.
What is geometrical shape?
Geometrical shapes are the figures which represent the forms of different objects. Some figures are two-dimensional, whereas some are three-dimensional shapes. The two-dimensional figures lie on only x-axis and y-axis, but 3d shapes lie in x, y and z axes. The z-axis shows the height of the object.
What are the three dimensional shapes?
Most of the three-dimensional shapes can be defined as a set of vertices, lines that connect the vertices and faces enclosed by these lines including obtained interior points. For many three dimensional shapes, faces are two-dimensional. Also, some shapes in three-dimensions have curves surfaces. In three dimensions, the primary shapes are:

Important parts of a pyramid
The base is the polygon in which the pyramid stands. The base can have different geometric shapes. For example, if the base is a triangle, the pyramid is called a triangular pyramid and if the base is a hexagon, the pyramid is called a hexagonal pyramid.
Different type of pyramids
There are a great variety of pyramids. We can form different pyramids by using different geometric shapes on the bases. A pyramid is named with respect to the figure at its base. The following are some of the most common pyramids along with their diagrams.
Important formulas for pyramids
Pyramids are three-dimensional geometric figures, so their most important formulas are the volume formula and the surface area formula.
Overview
Geometry (from Ancient Greek γεωμετρία (geōmetría) 'land measurement'; from γῆ (gê) 'earth, land', and μέτρον (métron) 'a measure') is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a geometer.
History
The earliest recorded beginnings of geometry can be traced to ancient Mesopotamia and Egypt in the 2nd millennium BC. Early geometry was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts. The earliest known texts on geometry are the Egyptian Rhind Papyrus (2000–1800 BC) and Moscow Papyrus (c. 1890 BC), an…
Main concepts
The following are some of the most important concepts in geometry.
Euclid took an abstract approach to geometry in his Elements, one of the most influential books ever written. Euclid introduced certain axioms, or postulates, expressing primary or self-evident properties of points, lines, and planes. He proceeded to rigorously deduce other properties by mathematical reasoning. T…
Contemporary geometry
Euclidean geometry is geometry in its classical sense. As it models the space of the physical world, it is used in many scientific areas, such as mechanics, astronomy, crystallography, and many technical fields, such as engineering, architecture, geodesy, aerodynamics, and navigation. The mandatory educational curriculum of the majority of nations includes the study of Euclidean concepts …
Applications
Geometry has found applications in many fields, some of which are described below.
Mathematics and art are related in a variety of ways. For instance, the theory of perspective showed that there is more to geometry than just the metric properties of figures: perspective is the origin of projective geometry.
