Have you ever struggled to make a square root without a calculator? Well, there is a way to make a square root by paper folding/compass. This technique is simple and easy to follow, and it can be done using only a few materials. In this article, we will guide you through the steps of making a square root by paper folding/compass.

Materials Needed

The materials needed for this project are:

A sheet of paper
A ruler
A compass

Step 1: Draw a Line

Start by drawing a line that is the length of the square root you want to make. For example, if you want to make the square root of 16, draw a line that is 4 units long.

Step 2: Fold the Paper

Next, fold the paper in half so that the line you drew is on the fold. Make sure that the line is in the center of the fold.

Step 3: Use the Compass

Take your compass and set it to the length of the line you drew. Place the point of the compass on the fold of the paper, where the line is located.

Step 4: Draw a Circle

Draw a circle with the compass, making sure that the circle intersects the line you drew on the paper.

Step 5: Fold the Paper Again

Fold the paper again so that the circle is on the fold. Make sure that the circle is in the center of the fold.

Step 6: Draw a Line

Draw a line from the center of the circle to the point where the circle intersects the line you drew on the paper.

Step 7: Measure the Line

Measure the length of the line you just drew.

Step 8: Divide the Line

Divide the length of the line by 2. This will give you half of the square root.

Step 9: Double the Length

Double the length that you got from step 8. This will give you the full length of the square root.

Step 10: Check Your Work

Check your work by multiplying the length of the square root by itself. It should equal the number you were trying to find the square root of.

Step 11: Practice

Practice this technique with different numbers to become more comfortable with it.

Step 12: Tip

If you are having trouble with the compass, try using a protractor instead. Set the protractor to the angle that the line makes with the fold of the paper, and then draw a line from the center of the circle to the point where the circle intersects the line you drew on the paper.

Step 13: Caution

Be careful when using the compass or protractor, as they have sharp points.

Step 14: Enjoy

Enjoy the satisfaction of being able to make a square root by paper folding/compass!

Step 15: Conclusion

In conclusion, making a square root by paper folding/compass is a simple and easy technique that can be done with only a few materials. By following the steps outlined in this article, you can make a square root without a calculator. This technique is useful for those who want to challenge their math skills and for those who want to impress their friends with their math abilities.

Happy folding!
