Horizontal and vertical lines interactive worksheet - Free Printable

Looking at the robot's legs, I can identify:

- Horizontal lines: The top edge of the legs (where they connect to the body), the bottom edges of the feet, and the horizontal line across the middle of the "X" inside each foot.
- Vertical lines: The outer edges of each leg.
- Diagonal lines: The diagonal lines that form the "X" inside each foot.

Now I have plenty of examples to select 3 of each type. Let me summarize my findings:

Horizontal Lines (3):
1. The top edge of the robot's head
2. The bottom edge of the robot's head (which is also the top of the mouth)
3. The top edge of the robot's body

Vertical Lines (3):
1. The left edge of the robot's head
2. The right edge of the robot's head
3. The left edge of the robot's body

Diagonal Lines (3):
1. The left antenna extending from the head
2. The right antenna extending from the head
3. The diagonal line from top-left to bottom-right inside the body's "X"

This completes the task of labeling 3 horizontal, 3 vertical, and 3 diagonal lines in the picture.
