How many letters in the word MATHEMATICS have more than one line symmetry
vertical line symmetry: M, A, T, H, I
horizontal line symmetry: H, E, C
none: S
so, more than one line: H
looks like the " I " also fits vertical as well as horizontal symmetry

To determine the number of letters in the word "MATHEMATICS" that have more than one line symmetry, we need to first understand what line symmetry is.
Line symmetry, also known as reflective symmetry, occurs when a shape or pattern can be divided into two equal halves that mirror each other. In the context of letters, line symmetry refers to whether a letter can be split into two equal halves along a vertical line, where each half appears as a mirror image of the other.
To find the number of letters in "MATHEMATICS" with more than one line symmetry, we can analyze each letter individually:
1. M: M has vertical line symmetry. When divided along a vertical line, each half is a mirror reflection of the other.
2. A: The letter A has a horizontal line of symmetry, but it does not have vertical line symmetry. It cannot be divided into two equal halves along a vertical line that mirror each other.
3. T: T has vertical line symmetry. Each half of the letter is a mirror image of the other when divided vertically.
4. H: H has neither vertical nor horizontal line symmetry. It cannot be divided into equal mirror halves in any direction.
5. E: The letter E has both vertical and horizontal line symmetries. When divided along a vertical line, each half is a mirror reflection of the other. The same applies when divided horizontally.
6. M: As mentioned earlier, M has vertical line symmetry. Each half is a mirror reflection of the other.
7. A: As mentioned earlier, the letter A does not have vertical line symmetry. It cannot be divided into two equal mirror halves along a vertical line.
8. T: As mentioned earlier, T has vertical line symmetry. Each half of the letter is a mirror image of the other when divided vertically.
9. I: I has vertical line symmetry. Both halves are identical when divided along a vertical line.
10. C: C does not have vertical line symmetry. It cannot be divided into two equal mirror halves along a vertical line.
11. S: S does not have vertical line symmetry either. It cannot be divided into two equal mirror halves along a vertical line.
Considering the analysis of each letter, there are a total of 5 letters in the word "MATHEMATICS" - M, T, E, I, and T - that have more than one line symmetry.
