1. ## Drafting

I had to go to drafting classes (company policy, once a year)

Our teacher decided to give us a little homework.

How can you divide a circle in 8 "CONGRUENT" (exact the same) pieces with only 3 straight cuts.

I give up.......do you????

Jorge

2. Are you sure He said exactly the same?

3. If you can re-arange the pieces as you go..........
Cut the circle in half, and stack the half circles...
Cut the half circules in half and stack the quarter circles...
Cut the quarter circles in half...
You now have 8 exact pieces.

4. That is it.

I can not find anything else.

Thank you

Jorge

5. Has this circle got a thickness? if so then slice down the edge so you got two disks, slice across the diameter up and down and there ya go 8 pieces.

Proly not, but it is friday...

6. 2 x 2 x 2 = 8 where x is the "line cuts" where the circle is being cut into the 8 parts.

Now if you really want to screw with the teacher, ask him how to do the EXACTLY same thing only this time making 2 cuts.

Answer: overlap fold it into halves 3 times. Then slice precisely down the lengths of the 2 exposed folds.

Result: 2 cuts, 8 congruent pieces.

7. Tank you all for your help.
