The word 'geometry' means measurement of the earth.Various shapes and figures with which we deal in Geometry are called geometrical figures.In geometry, we learn about the construction of geometrical figures and study their properties. Thus, we can say that geometry is the science of properties and relations of figures.

It is represented by any capital letter such as A,B,P,Q etc.

The symbol for a line is ↔. We call it line PQ and write it as arrow over PQ. Minimum of two points are needed to form a line. In this case PQ is a line.
