How to Trisect a Angle

By William Kofoed

Try it on real paper

And if you say it can't be done then

Disprove it on real paper with a real compass and straight edge

Step 1. Make an angle

Step 2. Draw a circle

Step 3. Make intersections of the lines and the circle and draw a segment between them and bisect it.

Step 4. Then bisect one of the new segments

Step 5. Then draw perpendicular lines through the intersections

Step 6. Then draw a smaller circle

Step 7. And make intersections with the line

Step 8. Then make a segment between the two intersections

Step 9. Then make an intersection

Step 10. Then draw perpendicular lines through the intersection

Step 11. And make intersections with the line

Step 12. And then make two segments

Step 13. And bisect them

Step 14. Then draw perpendicular lines through the intersections

Step 15. Then make an intersection and draw a circle through the intersection on the smaller circle

Step 16. Then make an intersection between the two circles

Step 17. Then make an intersection between the circle and the line and make a small circle and a intersection between the small circle and the larger circle

Step 18. And make another intersection between the small circle and the larger circle

Step 19. Then clean it up

Step 20. And draw two lines

Step 21. And clean it up again
