I don’t really know how to do this question. I tried it out, but I can’t seem to figure out how to construct the perpendicular line that passes through A. Can anyone help?
1. Draw an arc around your point that intersects the line (green)
2. Draw 2 arcs from where the first arc intersected the line (red)
3. Draw a line through the point where those 2 arcs intersect each other (blue)
