Mathematically, mensuration deals with different shapes in 2D and 3D concerning their shapes, sizes, area, length, height, breadth, volume, surface area, and lateral surface area. Since it deals with several factors, it has formulas for each. Mensuration applies to any closed figure with sides and vertices. It is a concise way of constructing a closed figure’s different properties and features. Defining mensuration outlines the properties as per the shape, size, and density of both 2D and 3D closed geometric figures. Mensuration also studies the difference between 2D and 3D figures as they are associated with different numbers of planes.
1D Figures
These are simple geometric figures which exist in only one dimension. They use only one measurement. Examples of one dimension figures are
- A line (an arrow at its end encloses it).
- A line segment (a point encloses it at its ends).
- A ray (it originates from a point at one end and extends through an arrow at another).
Difference between 2D and 3D figures
Conclusion
Mensuration has a simple concept. It covers all the geometric properties of 2D and 3D figures. Although there are many formulas to remember while solving questions based on this topic, it becomes easier when we imagine how the formulas were derived as per the shape and requirement. Mensuration deals with the properties of all geometrically closed figures. Mensuration makes getting a one-stop solution for all the formulas required to solve with geometric figures easier.
