This is a printable image illustrating how to draw a regular pentagon, in a number of steps, using a compass and ruler and a triangle. You could easily omit the use of triangle, in order to get a strict "by ruler and compass" construction, since the perpendicular lines at steps 5 and 6 could be constructed quite simply by the compass and the ruler alone, albeit more steps would be required.
