parallel lines geogebra

I Drew line AB and point C, not on line AB, through which a parallel line will be drawn. I then used the Line through Two Points and New Point button. I then seen that Line AB is shown with point C above it. I Used the Line through Two Points button to draw a line through point C that intersects line AB. Line CD is intersecting line AB now . I then marked a point of intersection between line AB and line CD with the Intersect Two Objects button. Point E indicates the point of intersection between lines AB and CD.I then Drew a circle with center point E that has a radius identical in length to segment DE. I Selected the Compass button and then points E, D, and E in order. After constructing that .Circle E passes through point D. Still using the Compass tool, I drew a second circle the same radius as circle E with the center at point C. In order, I selected points E, D, and C. I the seen that circle C intersects circle E in two locations. I then Indicated the points of intersection between circle E and lines AB and CD with the Intersect Two Objects button. I discovered that circle E intersects line AB at points H and I. I marked the points of intersection between circle C and line CD. Now that circle C intersects line CD at points J and K. I then used the Compass tool once again. I Selected points F and I, and then point J. It created a circle with a radius identical in length to the distance between points F and I, with a center point J. Circle J appears intersecting circle C in two points. I marked the points of intersection between circle C and circle J using the Intersect Two Objects button. Circle J intersects circle C at points M and L. I then Drew line CL with the Line through Two Points button. Now Line CL appears.
