Which statement is true E ?

B) The letter has a reflection symmetry only

Which statement is true Z?

A) The letter has rotation symmetry only

Which statement is true X?

D)The letter has both reflection and rotation symmetry

Step-by-step explanation:

If you rotate the letter, around its center, and at some point of the rotation the object looks exactly like it was at 0° or 360°. Then we can say that the letter has rotational symmetry.

The reflection symmetry is when you can find a line that divides the object in two half, and these half are the reflection of each other.

In the case of the letter E, if you draw a line that divides the letter in the upper half and lower half, the upper half is the reflection of the lower half. But letter E doesn't have rotation symmetry. (The letter has a reflection symmetry only)

For the letter Z, if you rotate the letter 180° it will look the same, but no line gives halves that are the reflection of the other. (The letter has rotation symmetry only)

Finally, with letter X, you can find two lines that divide the letter into halves that are the reflection of the other half (one at 0° an another at 90°). When you rotate the letter, it will look the same every 90° you rotate. (The letter has both reflection and rotation symmetry)
