2d mensuration handwritten notes 

Mensuration is a branch of mathematics in which we deal with the calculation of length, breath, height, area, volume and so on. Mensuration is mainly divided into three parts: One is Area, second is Volume and third is Perimeter. In this module, we will study about the measurement of 2D figures or plane figures.
In this article, we are going to cover the key concepts of Mensuration 2D along with the various types of questions, and tips and tricks. We have also added a few solved examples, which candidates will find beneficial in their exam preparation. Read the article thoroughly to clear all the doubts regarding the same.

Mensuration Maths – Definition

A section of mathematics that communicates the length, volume, or area of various geometric shapes is termed Mensuration. These shapes or patterns exist in two dimensions or three dimensions.

Mensuration in Maths- Important Terminologies

Let us discover a few more definitions linked to the various geometric shapes.

Terms	Abbreviation	Unit	Definition
Area	A		The area is the surface that is covered by the closed shape.
Perimeter	P		The measure of the endless line by the boundary of the presented figure is called a Perimeter.
Volume	V		The space utilised by a 3D shape or object is termed a Volume.
Curved Surface Area	CSA		If there is a curved surface/shape/object, then the total area obtained is called a curved surface area.
Lateral Surface area	LSA		The total area of all the lateral surfaces that encloses the presented figure is termed the lateral surface area.
Total Surface Area	TSA		The aggregate of all the curved and lateral surface areas is designated as the total surface area.
Square Unit	–		The area incorporated by a square of the length of one unit is termed a square unit.
Cube Unit	–		The volume involved by a cube of one side one is termed a cube unit.

Triangle

A triangle is a three sided closed plane figure. The sum of three interior angles of any triangle is always equal to 180 degree. Triangle can be categorized on the basis of sides as well as on the basis on angles.
