Origami Pentagon Base
It is difficult enough to imagine how a pentagon can be made from a square sheet of paper. However, the art of origami has existed for more than a century, so this problem was successfully solved. Such a base will definitely come in handy in the future, as it will serve as the basis for many interesting figures.
Fold the left corner to the right, but crease the fold not completely, but only in the place indicated by the dotted line.
Referring to the photo, bend the shape so the IG and BD create a right angle, and the paper is vertical.
Open the paper to see that your pentagon is complete. Add this base to your collection to be ready to fold the most unusual origami.
