Two lines that meet at 90 degree angles
WebAnswer: Start by making a line along the straight edge of the ruler. The more exacting way uses the fact that a line connecting the intersection of the arcs of two circles with the same radius and the line that connects the center of those circles are perpendicular. To draw this: * Make two po...
