					Constructing Parallel Lines
Parallel lines through a given
point
Parallel Lines
Step 1
  Begin with a given line and a point P
  above the line

               .P

                                          l
Parallel Lines
Step 2
  Through point P, draw a line that
  intersects line l.
  Label that point A.

             .P
         A                            l

                 Step 3
                   Open the compass
                   the size of line
                   segment AP.

Step 4
  Draw a circle around
  the angle formed.
Parallel Lines
Step 5
  With the same
  opening of the
  compass, draw a
  circle with the
  pointer of the
  compass on point P.

                 Step 6
                   Keeping the same
                   opening of the
                   compass, place the
                   point of the
                   compass on point X
                   and draw a circle.

                 Step 7
                   At the point of
                   intersection for both
                   circles, label the point
                   Y.
                   Draw a line from point P
                   to point Y.
                   You have constructed
                   parallel lines.
