FOLD THE RULER / Ruler

FOLD THE RULER
FOLD THE RULER

As a student, we often encounter a problem : how to draw a common
angle if we do not carry the triangle ruler. In fact, this is not easy at all.
So there is a way to simplify the problem by "drawing an angle".
This method uses an intuitive and simple way. You just need
to fold it and draw a sharp angle. It's that simple !!!
