Definition:
Geometry is the defined as the study of the size, shape and position of 2 dimensional shapes and 3 dimensional figures. However, geometry is used daily by almost everyone. Geometry begins with undefined items, definitions, and assumptions; these lead to theorems and constructions. It is an abstract subject, but easy to visualize, and it has many concrete practical applications. Please express your views of this topic What is a Acute Angle by commenting on blog.
Geometrical objects:
Point
A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter. A point represents position only; it has zero size
Line
A line can be thought of as connected set of infinitely many points. It extends infinitely far in two opposite directions. A line has infinite length, zero width, and zero height. Any two points on the line name it. The symbol ↔written on top of two letters is used to denote that line. A line may also be named by one small letter
Collinear points
Points that are lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are non-collinear points.
Plane
A plane has an infinite set of points forming a connected flat surface extending infinitely far in all directions. A plane has infinite length, width, and zero height (or thickness). It is usually represented in drawings by a four-sided. A single capital letter is used to denote a plane. The word plane is written with the letter so as not to be confused with a point . Is this topic How to find Area of a Circle hard for you? Watch out for my coming posts.
Postulates:
Postulate 1: A line contains at least two points.
Postulate 2: A plane has at least three non-collinear points with it.
Postulate 3: If we cross through any two points, there is exactly one line.
Postulate 4: If we cross through any three non-collinear points, there is exactly one plane.
Postulate 5: If two points lie in a plane, then the line joining them lies in that plane.
Postulate 6: If two planes intersect with each other, then their intersection is a line.
