Find the alphabets in the box which have no line of symmetry. A M P E D I K O N X S H U V W Z

The line of symmetry can be defined as the axis or imaginary line that passes through the centre of the shape or object and divides it into identical halves. Some alphabets posses vertical line of symmetry while some shows horizontal line of symmetry. While some alphabets show both vertical as well as horizontal lines of symmetry. The alphabet O has infinite numbers of lines of symmetry. The following alphabets doesn’t show any type of symmetry. F , G , K , J , L , N , P , Q , R , S , Z Hence, the alphabets which have no line of symmetry are P , N , S , Z .

Find the alphabets in the box which have rotational symmetry. A M P E D I K O N X S H U V W Z

The line of symmetry can be defined as the axis or imaginary line that passes through the centre of the shape or object and divides it into identical halves. An object is said to have a rotational symmetry if it looks the same after being rotated about its centre through an angle less than 360 ° . The number of positions in which a figure can be rotated and still appears exactly as it did before the rotation, is called the order of rotational symmetry. There are many capital letters of English alphabets which has symmetry when they are rotated clockwise or anticlockwise about an axis. Some of them are Z , H , S , N and O . When these letters are rotated 180 degrees clockwise or anticlockwise the letters appears to be same. Hence, the alphabets which have rotational symmetry are I , O , N , X , S , H , Z .

Find the alphabets in the box which have reflection symmetry. A M P E D I K O N X S H U V W Z

Reflectional symmetry is a type of symmetry in which one half of the object is the mirror image of the other. A figure may have both horizontal and vertical lines of symmetry. Letters like A , M and U appear the same in their mirror image. The letters A , H , I , M , O , T , U , V , W , X and Y appear the same in their mirror image. All the other letters of the alphabet appear reversed in their mirror image. Here are some examples given. The alphabets which have reflection symmetry are A , M , E , D , I , K , O , X , H , U , V , W .
