Geometry is the object-oriented part of mathematics and basic geometry is the foundation of geometry.
You will have learned basic geometry concepts.
You will have learned basic geometry definitions.
You will be introduced to basic geometry shapes.
Geometry basics is easy to learn. You will enjoy it.
Basic Geometry Concepts
Geometry is the structure of objects in terms of shape and size.
Are you interested in playing with objects in different shapes and sizes or love to drawing and sketching?
If so, geometry is perfect for you. Let's go to learn geometry basics step by step.
Wait..! Would you mind if this geometry lesson is explained explicitly. Well.
A rectangle is moving around a circle.
To study geometric dimension is prerequisite to understand geometry basics. In the same way, to study the following topics those are parts of elementary geometry is prerequisite to understand geometrical dimension.
A Point is nothing but a position. It has no length or width. So, a point is of no dimension or zero dimension.
A Line is the set of points that extends along a straight path infinitely on and on its opposite direction. It has only length (breadthless length). So, a line is of 1 dimension or simply one d.
A Plane is the two dimensional flat surface that goes on infinitely. It has only length and width. So, a plane is of two dimension.
A Solid has length, width and height or depth. So, a solid is of 3 dimensional geometric shapes.
Therefore, a clear concept of geometrical dimension is must to understand high school geometry.
Geometry discusses the relative position of figures. Basic geometry includes dimension. Zero dimensional or no dimensional geometry is concerned with point. A point is nothing but a position. It has no length, width or heigth. One dimensional geometry is relevant to distance. Because it has only length. Two dimensional geometry is invloved all about area. Because it has only length and width. And 3 dimensional geometry is invloved with volume or space. As volume or space consists of length, width and height.
Origin of Shapes
Basic Geometry Definitions
A line is the set of points that extends along a straight path infinitely on and on its opposite direction.
Another way ...
A line is a continuous extent of straight length infinitely far on and on its opposite direction without width or depth.
Thus a line includes:
We covered line segment and ray in geometry in another tutorials.
So a line, strictly speaking, is perfectly straight and has no ends in both directions.
It has only length.
So, a line is of one dimension and sometimes called one d.
A line is shown in the figure that extends infinitely in both directions.
Suppose A and B are two distinct points on the line.
It is read AB is a line and denoted by
If you arrange a set of lines one after another, it produces a plane.
A plane is all about two dimensional flat surface that expands infinitely.
A figure formed by two rays, inclination to each other, sharing a common endpoint is called an angle. The rays are known as the sides of the angle and the common endpoint is called the vertex of the angle. The measurement of angle is equal to how much two rays or sides are inclined to each other.
A curve is a smoothly-flowing path that may be straight or not. If the curve is straight, it is a line. So, a line is always a curve. Again, if the curve is not straight, it always changes its directions. This type of curve is a one dimensional figure.
A surface is a two-dimensional figure that may be flat or not. A circle, for instance, is a flat surface whereas a sphere is a curved surface. Thus a surface is a generalization of plane; as the plane is a flat surface.
Space is the set of all 3-dimensional points. Space consists of infinite number of points as well as infinite number of planes. In a nutshell, space is the 3-dimensional boundless extent.
Therefore, all objects in space have the relative position and direction.
And objects in space are called solids.
Types of Basic Geometry
Geometry is generally divided into two parts:
Plane geometry is all about the geometry of two dimensional geometric shapes.
In mathematics, plane geometry generally refers to Euclidean plane geometry.
This geometry lessons are helpful for those people who are involved in teaching and learning geometry in institution.
Points, line, triangle, quadrilateral, circle, ellipse, parabola, for instance, all are basic geometry shapes under plane geometry that can be drawn on a piece of paper or on a plane.
Plane geometry is also familiar with high school geometry as it is taught in secondary schools all over the world.
