How to construct parallel lines in geometry

You can use any of the methods described above. The axiom in non-Euclidian Geometry is that parallel lines intersect at infinity.

How to Construct Two Parallel Lines

It doesn't matter if the point is on another line; technically, every point is on an infinite number of lines, even if no line is shown. It does not matter how wide you set the compass, as long as it can intersect the given line.

If these instructions are hard to follow, just experiment with the triangle, and you'll figure it out. To do this, open the compass a little wider. So use the given point and ignore the second given line. By continuing to use our site, you agree to our cookie policy.

Set the width of the compass to the width of the first angle you created. Impressive publishing waterfall event. Using the same compass width, set the compass at the third vertex, and draw an arc that intersects the first arc you drew through the second vertex. Your reader, A.

Then, construct a line perpendicular to CD and passing through D. The construction above shows the creation of congruent corresponding angles which make the lines parallel.
