How would I construct a line perpendicular to a point on a line

Question

If given a total of 3 lines or circles to work with. One of the three objects must be the perpindicular line itself. So max of 2 circles. Max 3 lines. But only 3 total of a combination. 

 

Assume measurements cannot be made i.e. no ruler, and do sp with only a straightedge and compass.

Answer 1

There is a well known compass-and-straightedge method for the construction of a perpendicular to a point on a given line. Consult any STANDARD GEOMETRY TEXTBOOK(pre-Common Core) or Google to find details of CONSTRUCTING A PERPENDICULAR TO A LINE AT A GIVEN POINT ON THE LINE.

 

The following part of your question is very poorly written, and ought to be ignored:

If given a total of 3 lines or circles to work with. One of the three objects must be the perpindicular line itself. So max of 2 circles. Max 3 lines. But only 3 total of a combination.

Answer 2

1) draw line

2) select point

3) put pin of compass on point

4) open compass and "arc" line on both sides of point

5) move pin of compass to one arc

6) open compass more

7) make "arc" above and below point.

8) do 5, 6, 7 for other point

9) connect "arcs" above and below point.
