project due in two days...i need last minute help...how do you create the parallel? -Xav

Construct a line parallel to a given line through a given point not on the given line.

Let P be a point not on line k.

Make a segment AB on line k.

Construct the perpendicular bisector of segment AB (call the midpoint C).

Draw segment AP and ray BP. Ray BP intersects the perpendicular bisector at a point X. Draw ray AX.

Segment AP and the perpendicualr bisector of segment AB intersect at a point Y. Make ray BY.

Rays BY and AX intersect. Connect this intersection point and P.

Why does this work?

For the fourth one (perpendicular bisector of a given segment (where the length of the given segment is less than the distance between your parallel lines), you can make it exactly the same thing as the second one, where the length of the given segment is greater than the distance between your parallel lines...i think...

Now I just need one more...

never mind...

how long should the write up be??

As long as you can answer the question, it doesn't have to be a certain length :]

Sheldon told me one thing about the parallel line with the given point and give line and it was exactly one thing...literally.
The word: Parallelogram
Gonna bust it out tomorrow xd

um...isnt the construction..." a line parallel to a given line through a point NOT on the given line"...not with a given point?...iono...im tired.
