How can we use the concept: Horizontal lines extend from left to right.
Vertical lines extend from top to bottom.
Useful connections:
The place where the sky seems to meet the land is called the horizon. It goes left to right just like a horizontal line.
The bones in your spine are called vertebrae. They go up and down just like a vertical line.
Sample Math Problems
1. What is the first letter in the alphabet that has only vertical and horizontal lines? Use only capital letters.
Solution
Examine each letter of the alphabet starting with A until a letter matching the description is found.
A-has one horizontal line but two lines that are neither horizontal or vertical because they do not go straight across or directly up and down.
B-has one vertical line but also two curved lines, horizontal and vertical lines cannot be curved
C-has no vertical or horizontal lines, only one curved line
D-has one vertical line and one curved line
E-Has one vertical line and three horizontal lines. It has no curved lines or slant lines. It is the first letter of the alphabet that has only vertical and horizontal lines
2. How many vertical lines are in this image?
Solution
The blue lines are vertical. There are three vertical lines.
3. Problem Is it possible to make a triangle with two horizontal lines?
Solution
No, a triangle is a closed figure with only three sides. There is no way to connect two horizontal lines using only one more line to create a closed shape.
4. Sometimes people write letters using only vertical and horizontal lines. These are called block letters. Draw the first letter of your name using only horizontal and vertical lines.
