 # 8th Class Chapter No 4 - Practical Geometry in Maths for CBSE NCERT

Geometry (from the Ancient Greek: γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. In its simplest form, geometry is the mathematical study of shapes and space. Geometry can deal with flat, two-dimensional shapes, such as squares and circles, or three-dimensional shapes with depth, such as cubes and spheres. Before diving into two-dimensional and three-dimensional shapes, consider the basic geometric objects that create these shapes: points, lines, line segments, rays, and planes. A point is represented by a dot and shows a location in space. A line is a set of straight points that extends forever in both directions as depicted by arrows on both ends. Rays are lines that end on one side. Line segments end on both sides. Planes are surfaces that extend forever in all directions.
