What kind of line goes up and down?
- A line that goes up and down is called a vertical line.
- It stands straight from top to bottom.
- Vertical lines do not go sideways at all.
Examples:
- A flagpole:
- The pole stands straight up into the sky like a vertical line.
- Flags are hung on the top, and the pole is tall and straight.
- A tall tree:
- When you look at a tall tree, it goes up from the ground to the sky.
- The trunk of the tree looks like a vertical line too.
- A tower:
- Many towers, like radio towers, are very tall and straight up.
- They have a vertical shape, going up and down without bending.
