Today i am teaching class graph.
Mirror of symmetry
Today i am teaching class mirror symmetry.
Mirror line symmetry
When we look into a mirror we see our image is behind the mirror.The image is due to reflection in the mirror.We know that the image is formed as far behind the mirror as the object is in front of it.
In the figure if a mirror is placed along the line at the middle the half part of the figure reflects through the mirror creating the remaining identical half.
Line of symmetry
Today i am teaching types of symmetry.
Types of symmetry
1. Line of symmetry
2.Mirror of symmetry
3.Rotational symmetry.
1.Line of symmetry
When a line divides a given figure into two equal halves such that The left and right halves matchesexactly then we say that the figure is symmetrical about the line.This line is called the line of symmetry or axis of symmetry.
Symmetry
Today I am teaching symmetry.
Symmetry
Symmetry is an important geometrical concept commonly seen in nature and is used in every field of our life.
Artists Manufacturers designers architects and others make use of the idea of symmetry.The beehives flowers tree leaves hand kerchief utensils have symmetrical design.
For example if we cut an Apple into two equal halves we observe that two parts are in symmetry.
Rhombus
Today I am teaching construction of a rhombus.
Construction of a rhombus
I explain rhombus is constructed by splitting the figure into suitable triangles.First a triangle is constructed from the given data and then the fourth vertex is found.We need two independent measurements to construct a rhombus.
We can construct a rhombus when the following measurements are given
1.One side and one diagonal.
2.Two diagonal.
3.One side and one angle.
4.One diagonal and one angle.
