We use Rangoli Patterns in Maths to find symmetry and reflection.
It can be done by joining the dotted lines on the dot grid to find symmetry and the reflection of different figures.
In mathematics, the rangoli symbols go on expanding to form a line and the basic geometrical shapes like the circle, triangle, square, rectangle and so on
1. A dot grid is given below, you are required to draw a kite, leaf, flower, boat, star and a pot on it?
Ans: The required figures on the dot grid are drawn given below :
Shape Formation by Dot Grid
We can observe a kite, leaf, flower, boat, star and pot in the above figure.
Mirror ( or reflection ) symmetry divides a figure or design into halves that are mirror images.
In other words, objects are the same on both sides of a line ( usually in the middle).
Example of Mirror Halves are wings of Butterfly can be exactly get halved and Letter words like H, Y W X are the examples of Mirror halves as they can be exactly cut into two halves
1. Draw the Mirror halves of the following figures?
Figure(a) clearly shows the Mirror half of the capital letter A, and we have to draw the other mirror half of it. The required other mirror half is given below
Mirror Image of Half A
Figure(b) clearly shows the Mirror half of the capital letter D, and we have to draw the other mirror half of it. The required other mirror half is given below
Mirror Image of Half D
Figure(c) clearly shows the Mirror half of the capital letter N, and we have to draw the other mirror half of it. The required other mirror half is given below
Mirror Image of Half N
Figure(d) clearly shows the Mirror half of the capital letter H, and we have to draw the other mirror half of it. The required other mirror half is given below
Mirror Image of Half H
When the first half of an object reflects the other half of the object in the mirror, then we call it Reflection Symmetry.
Reflection Symmetry can also be named Mirror Symmetry.
For example, in general, human faces are identical on the left and right sides. The wings of most butterflies are identical on both sides, the left and right sides.
Finding Reflection Symmetry
The first half of an object must be a reflection of the other half of an object.
Imagine folding a rectangle along each line of symmetry and each of the half matching up perfectly, this is symmetry
For the two symmetrical halves, one of them follows lateral inversion, that is the left side appears to be the right side as it happens when you look in a mirror.
For Example The reflection of trees in clear water, and the reflection of mountains in a lake are among the commonly seen examples of reflection symmetry around us.
Q1. Draw some figures out of your imagination which can be exactly cut into two halves?
Q2. Below are some given pictures, and you have to think from what kind of view these pictures will seem like this?
Different Kinds of Views
Ans: Below is some required figures that can be exactly cut into two halves
Staircase - Side View is seen
Staircase - Top View is seen
Table - Top View is seen
Chair - Side View is seen
Pencil - Top View is seen
Bus - Side View is seen
