Parallel Lines
Parallel Line Construction
Follow these steps to construct a line parallel to AB through E
1) Using the POINT TOOL, mark point G anywhere on segment FB.
FG must be shorter than FE
2) Using the COMPASS TOOL, create a circle with radius FG and center point F.
Click on the COMPASS TOOL, then click F, then G, then F
3) Using the POINT TOOL, mark point H at the intersection of circle F and segment FE
H should be a black dot, not purple
4) Using the COMPASS TOOL, create a circle with radius FG and center point E.
Click on the COMPASS TOOL, then click F, then G, then E
5) Using the POINT TOOL, mark point I at the intersection of circle E and segment DE
I should be a black dot, not purple
(If I is too close to D use the MOVE TOOL to drag G closer to F to make the circles smaller)
6) Using the COMPASS TOOL, create a circle with radius HG and center point I
Click on the COMPASS TOOL, then click H, then G, then I
(If I is too close to D use the MOVE TOOL to drag G closer to F to make the circles smaller)
7) Using the POINT TOOL, mark point J at the intersection of circles E and I
J should be a black dot, not purple
There are two intersection points, one will make parallel lines, one will not...
7) Using the LINE TOOL, draw a line from E through J
