Geometry and Measurement

Geometry and measurements is the most important part of the mathematics. Geometry word is made from Geo and metria(Geo means earth and metria means for measurement) in this we are define the whole measurement of the earth. In this topic we are discussing the shapes, angles and turns, measuring length, perimeter, area, cubes, surface area and volume.

In analytic geometry problems we define a shape and its measurement. In the above shape five variables are use and all variables are connected to each other and make a triangle. In this diagram the three angles are of same length and some lines are symmetric, and one line is connected to the point A and point E, and makes a triangle.
In Geometry, measurements are used to describe all the circles and curves. In geometry we calculate the areas and circumferences of figures such as circles, rectangles, cubes, cuboids, etc.
The Geometry and measurement are mainly used to find the location of area on earth, when we go to an unknown area, we can see the map and find the proper location. In this we find the angle of any value.
When we draw a chart on a graph paper on any equation, we are actually using concepts of geometry. In grade XII students should know how to find total surface areas, curved surface areas, circumferences etc of figures like triangles, rectangles, pentagons, circles and other polynomials.

In upcoming posts we will discuss about Euclidean/non-Euclidean geometries in Grade XII and Central limit theorem. Visit our website for information on Maharashtra board syllabus class 11
