Trisect Challenge
Directions
Use Geogebra to find the trisect (one-third) point of a given segment
• The given segment AB must be the first object created on the screen
• Use MEASURE to demonstrate that your method works
• You may not use the feature called “dilate” in the transformations menu. All other menu items (such as
“construct midpoint” or “construct perpendicular” are fair game.)
• Email your solutions as soon as you get them to: kweber@headroyce.org or jfuentes@headroyce.org
• There are numerous ways to trisect a segment. You may hand in more than one solution. We will let you know if you found a truly new method or if you basically did the same thing again in a slightly different way.
Scoring
You need to find 4 possible methods for trisections for full credit.
Any additional methods will be counted towards extra credit.
Your submissions should SHOW all your circles
and segments.
Warning
• Please...do not cheat! You must avoid the temptation to peek at other student’s solutions or talk to your friends about this assignment. Furthermore, there are plenty of solutions on the internet - no peeking!
