Introduction: How to Make an Equilateral Triangle From a Square

By
Triangles are the strongest shapes in the world, due to the fact that with 3 lengths of sides, only one triangle can be made. This Instructable will teach you how to make a paper equilateral triangle out of a square without any tools. I was taught how to do this a while back but I have not seen any Instructables on how to do this.

Step 1: Start With a Square.

Materials:

  • A piece of square paper

Tools:

  • Scissors (optional)
  • Pencil (optional)
  • Tongue (If you do not have scissors)

Yes, all you really need are your hands, a square piece of paper, and your tongue.

Step 2: Fold in Half

Fold the square in half hamburger/hot dog style and then unfold.

Step 3: Left Corner to Center

Now fold the bottom left corner so that it goes over the center fold. Make sure that the edge of the paper goes from the right bottom corner to the center crease. Pinch where the former bottom right corner meets the center line.

Step 4: Make Two More Sides of the Triangle.

Make a fold that goes from where the pinch intersects the center to the bottom right hand corner, repeat on left side. These will become the two other sides of the triangle.

Step 5: Crease, Lick, Rip, Repeat

Now, sharply crease the right side of the triangle both ways. Then lick the crease and rip (or use scissors)

Step 6: The Triangle Is Finished

Below is the triangle, so now what do you do with it, Look to see in my next instructable.
