Explain the difference between a vertical and horizontal line of symmetry.

A vertical line of symmetry runs straight up and down, while a horizontal line of symmetry is flat, like the horizon.

Does the letter 'Z' have line symmetry? Explain your answer.

No, the letter 'Z' does not have line symmetry because there is no line along which you can fold it and have the two halves match.

I can identify and apply lines of symmetry in geometric figures.

1
Line symmetry is also known as reflection symmetry or mirror symmetry.
2
Rotational symmetry means that a shape can be rotated a certain amount and match the unrotated shape.
3
The order of rotation is how many times the shape matches in a complete rotation, and the angle of rotation is the smallest angle needed to rotate a shape for it to match the starting shape.
