| Text | A triangle is a polygon with three sides. This is a simple application of constructing any polygon.
Creation of a triangle without using the edges of the sheet 1. Create the support for the first side using a valley fold. Mark the fold well. The choice of the location of this first fold will be decisive for the rest of the operations. It is recommended to make a fold joining two adjacent sides, to have the largest possible surface area afterwards. 2. Choose a starting point on the fold you have just created. This starting point can be a starting point of the hinge fold, or a point on the hinge fold itself. It will determine the direction of travel of the polygon. 3. Create the support for the second side using a valley fold passing through the starting point you have just chosen. Mark the fold well. There is no reference to determine the angle that this fold will form with the previous fold. We can decide to form an acute, obtuse or right angle. 4. If the first previous side is hidden by an overflow of paper, make a mountain fold starting from the starting point that you have just used and resting on the previous side. Mark well and tuck under the flap. 5. Choose a starting point on the second side that you have just created and an ending point on the first side created. 7. Create the last side of the triangle using a valley fold passing through the two points you have just chosen. 8. Eliminate any excess paper using mountain folds resting on the contours of the triangle. Enter the surplus under the different sections. 9. Flip the fold from right to left. Here is your triangle, which has a smooth side. If it really has no properties (isosceles, equilateral, rectangle, etc.) it is called a scalene triangle. |
