Question

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?

Answer 1

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)
