Regular/irregular geometric shapes

In the geometrical mathematics, we all are very well aware that it is a collection of several kinds of shapes and figures. These figures and shapes are very helpful in solving various kinds of problem that are related to our daily routine life. In geometry, these shapes and figures are categorized into different category according to their properties like quadrilateral, circle, and polygons and so on. Here we are going to discussing about the geometrical shape 'polygon'. The concept of polygon helps the school's student to understand the geometrical concept very well. (know more about cbse latest sample papers , here)
Polygon is a geometrical shape which comes from the Greek word. Polygon word formed by the combination of two words, 'poly' which mean is “many” and 'gon' which mean is “angle”. A polygon is a shape that is drawn on the 2-D plane with help of straight lines or sides. In the simple mean we can say that polygon is the two dimensional shapes. These shapes are formed by straight lines and the shape is closed. It means that in this shape all the lines are connect to each other. In the polygon, according to the property of geometrical shape we can categorize the polygon into the following manner:
A) simplex or complex
B) Concave or convex
C)
Regular geometric shapes or irregular geometric shapes
Here we are going to discussing about the regular and irregular shape.
Regular geometric shapes are those shapes in which all the existing angles are equal and all the sides are equal. In the same aspect we can say that those figures whose existing angles and shapes are not equal in measure then these shapes are consider as a
Irregular geometric shapes. In the case of regular, equilateral triangle is the one of the best example because this triangle is made up of three straight sides, it is closed in shape and all the angles and sides are equal to each other. In the next session we are going to discuss Grade VII, Geometric concepts and In the next session we will discuss about Properties of 2-d and 3-d figures. 

Geometric concepts

As we all are very well aware that geometry is the one of the oldest branch of mathematics. It plays an important role in mathematics to solve various kinds of problem. The term “geometry” is comes from the Greek word “Geometron” which is formed by the combination of two word “Geo” and “Metron”. The word “Geo” refers to Earth and the word 'Metron' refers to measurement. The need of the  Geometric concepts was felt in several years ago when person realizes to measure their land when they want to sold or buy their land. The basic application of geometrical construction were made centuries before the mathematical principles on which construction were based and recorded.
In the basic concept of geometry we generally studied about the points, lines, planes, closed flat shapes and many others. These are the most basic concept of geometry that provides the helps in describing, designing and constructing any type of visible objects. In todays life, the concept of geometry used in various field like architects, engineers field, planning for constructing the buildings, bridges roads and many other geometrical architecture cal things. In the below we show you the some of the basic
Concepts of geometry:
A) Point: In geometry a point can be defined as a mark of point which has no length, no breath and no height. It occupies the position and location but no magnitude. This point helps in creating various other type of geometrical shape.
B) Line: The line can be defined as a distance between the two points. A line has no width. Usually a line refers as a straight line. (know more about icse board, here)
C) Line – segment: This line segment different form the line. In line segment, the part of a line with two definite end points is defined but in line these definite points are not define. These line segments are very helpful to form various geometrical shapes like square, rectangle and so on.
As like above there are other geometrical concept are defining in mathematics. Like interesting lines, parallel lines, perpendicular lines and so on. In the next session we are going to discuss Grade VII, Tessellations.
