SOF Olympiad Trainer is wrong. Look carefully. E is symmetrical. I has horizontal line of symmetry

Ans 5:

Class : Class 5
MASTER ANSWER!!!!!5 is correct because E also has a horizontal symmetrical line.

Ans 6:

Class : Class 5
Answer should be A

Ans 9:

Class : Class 5
Sure shot...... all the 5 letters - I,N,A,O,E... All these letters are symmetrical.... Wrong answer uploaded by the website..... Dissapointed....

Ans 10:

Class : Class 7
I agree with Bharat and Jyoti... e isn't symmetrical

Ans 11:

Class : Class 7
letter E is also an symmetrical on horizontal axis.

Ans 12:

Class : Class 6
Answer is a

Ans 13:

Class : Class 7
its true.answer should be six !!!

Ans 14:

Class : Class 5
O has infinate lines of symmetry, however in the question it has given „EXACTLY 2 lines of symmetry“

Ans 15:

Class : Class 5
55555!!!!!:(

Ans 16:

Class : Class 9
Letter E is also symmetrical

Ans 17:

Class : Class 5
answer is 4 because they asked for atleast 1 symmetry line

Ans 18:

Class : Class 7

Ans 19:

Class : Class 5
yes this sof is really bad and mad

Class : Class 7

Ans 21:

Class : Class 5
master . admmin to answer

Ans 22:

Class : Class 5
HAS TO BE A

Ans 23:

Class : Class 3
E is not symmetrical because if we see the gap the upper one has a small gap and the lower one has a large gap. That's why there is no symmetriy

Ans 24:

Class : Class 7
Wrong question the answer is 5

Ans 25:

Class : Class 3
The answer should be 5!

Ans 26:

Class : Class 8
The answer is clearly 5=I,N,A,O,E

Ans 27:

Class : Class 4
EEEEEEEEEEEEEEEEE.....................!!!!!!!!!!???????????

Ans 28:

Class : Class 7
The answer shoud be B)1 because O has infinite lines of symmetry and also check the solution and stop being dumb.Also E has also 1 line of symmetry but SOF has given the question.Please read the queston carefully.And they have also given an image so 5 would not be the answer.MASTER ANSWER

Ans 29:

Class : Class 5
5

Ans 30:

Class : Class 7
How r we supposed to know such a small difference E is symetrical

Ans 31:

Class : Class 5

Ans 32:

Class : Class 7
letter E is also an symmetrical on horizontal axis.

Ans 33:

Class : Class 8
E has horizontal line of symmetry

Ans 34:

Class : Class 9
I THINK IT IS A. E IS SYMMETRICAL. But Jyoti is also right

Ans 35:

Class : Class 8
No! Letter E is not symmetrical as the upper side of the E has lesser gap than that of its lower side. Therefore the ans is B.

Ans 36:

Class : Class 9
Guys Jyoti mehta from vibgyor high is correct because you see E the gapis lees in one and more in 2 one

Ans 37:

Class : Class 6
S

Ans 38:

Class : Class 6
S

Ans 39:

Class : Class 7
no its bstop being dumbits b because only i has two lines of symetryo has infinite lines of symetry this is a master answer stop writing 25 ans all were wrongask sof for help please!

Ans 40:

Class : Class 6
5- S,I,N,A,O

Ans 41:

Class : Class 6
S and E are symmetrical but in this font it is not

Ans 42:

Class : Class 7
0 alphabets of *exact* two lines of symetry

Ans 43:

Class : Class 3
Oh E letter is not symmetrical because the gap between to curves is not exactly same focus on E

Ans 44:

Class : Class 6
Let's analyze each letter in the word "MOTIVATE" to determine if it has exactly two lines of symmetry:M: This letter has only one line of symmetry, which is a vertical line passing through the middle of the letter.O: This letter has an infinite number of lines of symmetry, as any line passing through its center will divide it into two identical halves.T: This letter has one line of symmetry, which is a horizontal line passing through the middle of the letter.I: This letter has two lines of symmetry, which are a vertical line passing through the middle of the letter and another passing from the top.V: This letter has one line of symmetry, which is a vertical line passing through the top of the letter.A: This letter has one line of symmetry, which is a vertical line passing through the middle of the letter.T: This letter has one line of symmetry, which is a horizontal line passing through the middle of the letter.E: This letter has zero lines of symmetry, as there is a small gap between the first top two horizontal lines and a big gap between the last two horizontal lines.Also, in the question, SOF has clearly mentioned "which have exactly two lines of symmetry" This line proves that we need to find such an answer which supports and goes in agreement with the question.Therefore, only one letter in the word "MOTIVATE" have exactly two lines of symmetry, which is the "I" letter.I request SOF to correct the answer and give us the missing mark.

Ans 45:

Ans 46:

Class : Class 8
Ans is 4

Ans 47:

Class : Class 7
1 will be the correct answer because O has infinite lines of symmetry and the question said that how many of the following figures have exactly 2 lines of symmetry. The perfect answer and explanation.

Ans 48:

Class : Class 7
6 letters are symmetrical. Letters S, I, N, A, O, E

Ans 49:

Class : Class 5
how is N symmetrical!!!!!

Ans 50:

Class : Class 6
We need letters with EXACTLY TWO (2) lines of symmetry. Although "O" has infinite lines of symmetry, LOOK CLOSE WITH YOUR EYES PEELED, it is an oval shape, so only 2 lines.

Ans 51:

Class : Class 8
E is a symmetrical letter, but in this font it is not because of width on top and bottom

Ans 52:

Class : Class 6
S has no line of symmetry, neither horizontal nor vertical ,and it cant be symmetrical by a slanting line.E is also not symmetrical by a horizontal line because the gaps are not equal between them as shown in the picture

Ans 53:

Class : Class 6
I agree with Bharat and Jyoti, E is not symmetrical. I know that whenever we write E, like in the font in which I am writing now, it is symmetrical, but as per the question given, the font is different, and so, the letter E is not symmetrical. The curved gaps on top and bottom are very different and they are visible by the naked eye.

Ans 54:

Class : Class 9
options are wrong.6 is the answer

Ans 55:

Class : Class 9
this doesn't make sense E is also symmetrical

Ans 57:

Class : Class 3
No dragonite you are wrong, only 5 letters in the word are symmetrical not 6 : I ,N, A, O, E

Ans 58:

Class : Class 5
A , You all are right

Ans 59:

Class : Class 6
I agree with virat

Ans 60:

Class : Class 6
Answer should be A. S is symmetrical.

Ans 61:

Class : Class 5

Ans 62:

the answer is b - 5 = i,n,a,o,e
