Geometric Introduction

Introduction to geometry:
Geometry is one of the main branch of mathematics it deals with the pre algebra concepts.Geometry is the study of object; It contains the 2 dimensional objects and three dimensional objects. Geometry is the study of these objects size and shapes .Each object have different sizes and different shapes. Without geometry we cannot easily find the object shapes and size of an object. Main concept of geometry is line, angles, Line segment.

Basic concepts of geometry introduction:

Line
Line segment
Angles
Rays
Introducing geometric two dimensional objects:

Square
Rectangle
Triangle
Circle
Three dimensional objects:

Cube
Cylinder
Prism
Sphere

Basic terms of geometry Introduction:


Basic terms in geometry:

Introduction for line:

Line is nothing but straight line curve; It is a infinite length of one dimensional object. It plot the doubled direction, that Mean we can draw the line both direct and inverse direction

Introduction for line segment:

Line segment mean nothing but a one-dimensional, curved finite length  of the single direction line is called line segment.

Two types of lines:

Horizontal line
Straight line is called horizontal line

Vertical line
When the lines are stand at 90 degree called as vertical line

Comparison of two lines also classified into many types:

Parallel line
When the two lines stands opposites to each other called parallel line example Ladder)

Perpendicular lines
When one vertical line stands on horizontal line that is called as Perpendicular line.(example alphabet letter “T”)

Intersection line:
When two lines are intersected each other (Example: Alphabet x)


Basic terms of angles in geometry Introduction:


Angles:

Angle mean nothing but a Inclination of two line is called angles

Angles are classified in different ways:

Right angle
Right angle mean nothing nut a angle between two lines is 90 degree

Acute angle
Acute angle mean nothing but angle between two line s is < 90 degree

Abtuse angle
Abtuse angle mean only one angle should be > the 90 degree

Straight angle:
It is nothing but Horizontal line. Angle between the line is 180 degree

Other angles using in geopmety:

Supplementary angle
Complementary angle
Vertical angle
Reflex angle
