| Text | A triangle with a right angle is called a right triangle. In this case, the side opposite the right angle is called hypotenuse and the other two angles are the sides adjacent to the right angle. To construct a right triangle, all you need to do is create the second side perpendicular to the first. A triangle is a polygon with three sides. This is a simple application of constructing any polygon. Method 1 - Creating a right 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 and perpendicular to the first side. Mark the fold well. Simply fold down the flap that is formed, ensuring that the extension of the support on the first side comes on the first side itself. We thus obtain a right right angle bordered by two hinge folds. 4. If the first side is hidden by overflowing paper, make a mountain fold starting from the starting point 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. The largest rectangle triangle is obtained by choosing the intersections of the hinge folds with the borders of the sheet of paper. 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 series of mountain and valley folds resting on the contours of the triangle. Enter the surplus under the different sections. Another way is to cut out the excess paper in order to get a rectangle triangle with only one thickness. 9. Flip the fold from right to left. Here is a right triangle, which has a smooth side. Method 2 - using a square paper 1. Bring, by a valley fold passing diagonally, the upper right vertex to the lower left vertex. We obtain a rectangular triangular shape of double thickness. If you cut the sheet of paper along the fold you just made, you get two identical rectangle triangles. |
