Learn Class 4 Math - Geometry

Geometry is that branch of mathematics that has angles, shapes, dimensions, and sizes of several things that we generally see in our everyday lives. In Euclidean geometry, you will notice 2-D shapes and 3-D shapes.

In-plane Geometry 2, most shapes like a square, circle, triangle, and rectangle are considered. These are called Flat shapes. Several 3D shapes, just like Cube, Cuboid, Cone, etc., are considered in Solid geometry. These are called Solids. The basic geometry is based on line, plane, which is explained in the Coordinate geometry.

Several types of shapes in Geometry help us understand the shapes in our everyday life. With the help of these geometric concepts, it is essential to calculate the perimeter, volume, and area of shapes.

Branches of Geometry

  1. Algebraic Geometry – It is that branch of geometry that includes linear and polynomial algebraic equations used to determine the sets of zeros.
  2. Discrete Geometry – It is concerned with the corresponding position of simple geometric objects, such as points, lines, etc.
  3. Differential Geometry – It uses techniques of algebra and calculus for problem solving.
  4. Euclidean Geometry – The study of plane and solid figures based on axioms and theorems, including points, lines, planes, etc.

Geometry Formulas

To determine the area, perimeter, volume, and sizes using length, breadth, and height of various geometrical figures, geometry formulas are required.
