3 Cuts
Professor Mysteria went to his class and asked them to complete a problem.
"Using the square piece of paper in front of you, get 8 triangles of the same shape in 3 cuts, using the scissors only."
No one got the problem except for one person. How did they do it?
Answer
Cut the paper in half.
Stack the two pieces of paper and cut in half again.
Now you have four pieces of paper, stack again and cut diagonally. These are the 8 triangles.

| The only thing I don't understand why 3 cuts. It can easily be done with 2 cuts. |

| I can do it in one. It doesn't consume the whole sheet of paper, but I get 8 congruent triangles. |

| you could also form 8 triangles by folding it and then cutting. you never said you can't fold it |

| I was attempting to avoid the whole foldng thing with 'using the scissors only'. Clearly didn't work. |
